Make sure the launch range is clear of any obstructions. 2. Using the Plumb Bob and sticky note, mark the floor underneath the launch point. Measure the height of the launch point using the metric ruler once per person and take an average. 3.
When jumping, keep your hands by your side or in front of you for assistance in jumping and follow the same procedures just described. Step1: When beginning, bend down to a 1/4 squat position Step2: Turn the rope and jump back into the air to a minimum of 8 to 10 inches. (You may jump 10 to 12 inches if this is too easy). When you land this completes 1 repetition. Step3: Continue repeating this motion for each repetition.

Lab #2 – KINE 4315 Instructions for Administrating the YMCA Submax Cycle Protocol Pretest 1. Pre Test a. Write down 85% of max heart rate on test form b. Take weight, Take height c. Resting blood pressure, Resting heart rate d. Adjust seat height and record for future tests e. Set metronome at 50 bpm, Subject practices pace during warm-up 2. Test a.
If something is on the bridge the bridge has to apply the same force. For Example, a child could be applying a force to the Bridge by simply being on the bridge. The bridge pushes back up with the same amount of force. The force is in equilibrium when it does not move and it has a net force of zero. In order for our group’s popsicles bridge to hold 150 pounds, the bridge had to have the right structure.
The most recent recommendation from the National Academies of Science Institute of Medicine in which to maintain cardiovascular health at a maximal level, regardless of weight, adults and children should spend a total of at least ___ each day in moderately intense physical activity. a. 1 hour b. 45 minutes c. 30 minutes d. 20 minutes 11. Maximal heart rate can be estimated by subtracting the person's age (in years) from: a.
How does the rate of reaction in Task 2 compare with the rate in Task 1? Suggest a reason for the change. By comparing the two curves and the times taken to reach 0.0 g (the last times on the list), predict the time it would take for the reaction to finish if 100 chips were used. Task 3 Press back but not clear and change the number of chips to 100 but leave the acid concentration at 1.0 mol/dm3 . Click start and take readings as often as possible (by clicking the take readings button) until the mass reaches 0.0 g. Stop the reaction immediately.

2. What was your prediction about the results of each factor tested in your two lab procedures? Explain your predictions based on your knowledge of the dissolving process, collision theory, and reaction rates. I was thinking the balloon would inflate at a minimal pace but didn’t think the bottle would crush as result of it. Keeping the amount of water and time was imperative and double checking to make sure everything is right was prudent 3.
Usually, when the temperature of objects is decreased the densities are increased and vice versa. And so, to prevent these variations I could have taken the measurements when the pipes were all at the same temperature. In the future, a water displacement experiment could be used to calculate the volume of the pipes or other unidentified
