After all the trials are completed for the six distances, find the average time it took the ball to reach the end from each point. Repeat this process for the incline of the ramp set at 15°. The independent variables of this experiment are the distances from which you release the ball. The dependent variables are the times at which it takes the ball to roll to the end of the ramp starting from each distance. Cowan 2 At the 10° incline of the ramp for the distance of 96 centimeters (cm), the average time was 1.04 seconds (s).
The R-squared value shows us the correlation between the two variables in each graph that we were comparing. A consistent, precise R-squared value would be ideally 1. In all three cases, only one of our methods gave us this result: Titration. So given our results titration was the most precise method. But, our Ideal Gas Law method was more precise than crystallization from the previous week due to our newly found R-squared value of 0.8909.
Stress Analysis An important factor to determine is how much stress the stabilizing link needs to withstand. It was stated that the stabilizing link was designed to withstand 1G of lateral force. In order to have a lateral force of one G on the Bridgehampton race track, we calculated the car’s maximum speed in turn 11 to be 71 feet per second. This was done by estimating the radius of the turn from a map of the track to be 340.7 feet. This seems to be a reasonable value of speed in a hairpin turn.
The faster the acceleration is, the less mass it is. Also physics concepts relates to mousetrap cars because in physics we learned that, in order for the mousetrap cars to move, it must have force acting upon it (ground) which pushes the car up. So both the force of the ground and the force of the mousetrap car must be equal in order for the vehicle to work go forward. Physics concepts relate to mousetrap cars because Newton’s laws are involved in these mousetrap cars. Newton’s first law states that, “everybody continues in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impressed on it.” The mousetrap car relates to this because the mousetrap car does not move until the force of the mousetrap moves it.
In this study, there were 21 healthy joggers between the ages of 18 and 36 that were used. These participants were to run an eight and one half minute mile at seven miles per hours on a four degree incline, a four degree decline, and a normal level, so in total, three miles were being run by the participants. To monitor joint motion, retro-reflective markers were placed on the anterior and posterior iliac crests, the lateral femoral condyles, lateral mid-thighs, lateral mid-shanks, lateral malleoli, posterior calcanei, and second metatarsal heads. During the experiment, ground reaction force data was taken and so was kinematic data through a 10-camera motion capture system. These two things distinguished the movements of each joint and also the force each joint is producing during decline, incline, and normal running phases.
Record your prediction in your notebook. Hold the cart so the rear axle of the vehicles is at notch B on the ramp instead of notch A, and repeat steps 3-7. Predict what you think will happen to the block if the cart starts from notch C. Remember that realeasing the cart from notch C results in the slowest cart speed. Record your predictionin your notebook. Hold the cartaxle of the cart is at notch C on the ramp, and repeat steps 3-7.
To run The Electric Stampede they will have to charge the battery then connect the power turn on the receiver and speed controller and drive. While The Nitro Stampede requires them to fill the Nitro gas tank and connect the EZ-Start battery pack to warm the glow plugs and pull to start. Weather conditions can affect the driving and starting conditions for the Nitro Stampede whereas the Electric stampede the weather conditions has little to no affect at all on starting to driving
5. Design team called the DutchEVO “emotional sustainability” that led fun-to-drive message increasing the energy consumption. The trade-off between safety and sustainability were faced by the Engineers. The engineers wanted a lightweight car, meaning that all safety system should not be too heavy. Including airbags and safety systems used were disputed because will make a car heavy.
We removed one of the fishing lines, and timed how long the pendulum would take to swing back and forth ten times (ten periods). We chose to time it for ten periods rather than one because the data would be more reliable and consistent. After recording this time in our data table and dividing by the number of times we allowed the pendulum to swing (ten) to find the period, we repeated this process four more times, each time with a different length of string. We recorded the length and period for each of the five trials. Through both qualitative observation, and our quantitative data, we deduced that the shorter the length of a pendulum, the smaller its period.
Ford Motor Company is equipping the ford explorer with a 3.7 liter v-6 rather than the standard 3.5 liter v-6 which will pick up an extra 14 horse power and 24lb-ft of torque. In order for an officer not to lose a suspect during a pursuit the California Highway Patrol requires that their vehicles hit 120 mph from a standing point within two miles. When in a high speed pursuit you don’t just need performance which will allow you to keep up, but the engine in the vehicle must be reliable when going full throttle. The California Highway Patrol requires that the vehicle must maintain an open throttle for a minimum of 25 miles without causing any damage to the vehicle. The new Ford Explore exceeds in not just performance but in being reliable when it’s most
