Jessica Yan Rick St. Denis, Tyler Wiseman 13 September 2012 Projectile Motion: Ball in the Bin Purpose: The purpose of the experiment is to determine the velocity of a ball launched from the Projectile Launcher device, and then to use that velocity to find where on the floor the ball will land given a specific angle. Theory: Two-dimensional motion is as it sounds, made of the two components of Vertical velocity and Horizontal Velocity. Horizontal Motion can be described as constant, neglecting air resistance, and Vertical Motion is characterized by the acceleration of gravity pulling at 9.8m/s². In this particular experiment, the total velocity will be split into the two components in order to find the time in the air, and horizontal distance from the launcher. The motion of these components can be described as d=vt for constant horizontal motion, and d=1/2at² + Vit.
NOTE: If you are using ME-9215A Photogate Timers, use the memory function to store the initial times while the final times are being measured. Immediately after the final times are recorded, the gliders must be stopped to prevent them from triggering the photogate again due to rebounds. If not, have someone watching each photogate to record the initial times before the glider passes back through the photogate. ä ® 17 Photogate Timers 012-06379A Repeat the experiment several times, varying the mass of one or both gliders and varying the initial velocity of glider1. Try collisions in which the initial velocity of glider2 is not zero.
How high was the copter when the package hit? Honors Supplement 1. If, from a height of 62m, Galileo accidentally dropped one of the cannon balls 0.5sec before the other, with what velocity would the second ball I have to be thrown downward to reach the ground at the same time as the first ball? [-5.3 m/s] 2. A flowerpot is dropped and passes by a window below.
* The final speed was recorded by the light gate detector about three times for each height. * To record the speed, we held the trolley at the top of the ramp with the help of meter rule. Then, as the trolley rolled down at the end of the ramp, the light gate detected its speed in metre per second(m/s). * The average speed of the final speed was calculated by : Vavg of the final speed (Vf) = V1+V2+V3 (m/s) 3 * The final speed was recorded by the light gate detector about three times for each
You can conduct a web search with keywords “instructions for paper airplanes” to see some designs and the instructions for making them. Go outside, throw the plane and time how long in seconds the plane flies. Using a stopwatch or the second hand on your wristwatch, record the number of seconds from the time it leaves your hand until the time it lands on the ground. Using a meter stick, ruler, or tape measure, measure the distance the plane traveled. Record your measurements in the data table at the end of this document.
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).
21) One rock is dropped from the top of a cliff of height h at the same time as a second rock is tossed upward at speed v. if the rock that was tossed upward takes twice as much time to reach the ground as the one that was dropped, what was the initial speed, v, of the rock that was thrown (state in terms of g and h)? 22) A 0.50 kg cart moves on a straight horizontal track. The graph of velocity v versus time t for the cart is given below. a. Indicate every time t for which the cart is at rest.
Have two people fly it and see which plane goes the furthest, making sure to match the same amount of force used to throw the planes. Then, have one person to throw both planes and see if the results match, using the same force. Then switch persons and repeat. The controlled variable would be the how hard the plane was thrown. PART 2 Purpose: In this experiment I would like to see if the color of a bedroom affects the amount of sleep.
The dynamic strength test tests your upper body strength. Equipment used is called the ‘Dyno’. (Back strength test) You have to sit with your chest resting against the padding, grab hold of the handle and pull until your hands are level with your sternum. You’re allowed 3 warm up attempts and then you have five full pulls and the averages of all 5 pulls are recorded. The pass rate for this test is to be able to pull 35KG.
iVelocity and Acceleration Calculation Worksheet DIRECTIONS: Solve the following situation problems using equations for velocity and acceleration. 1 What is the speed of a rocket that travels 9000 meters in 12.12 seconds? 2 What is the speed of a jet plane that travels 528 meters in 4 seconds? 3 After an impact involving a non-functioning satellite, a paint chip leaves the surface of the satellite at a speed of 96 m/s. After 17 seconds, how far has the chip landed?
