2. You want to estimate from how high if it is safe to jump onto a concrete floor. For this, you consider impulse and the force of impact. If you jump from a chair of height of 0.50 m, and land on a concrete floor with stiff legs, it just starts to hurt. Therefore, you consider the average force on your body in such a landing to be your ‘safe limit’. In this case, you estimate that your body moves by about 0.75 cm during the landing. If you allow yourself to bend your knees upon landing on the same concrete floor, you are able to mitigate the force of impact. You estimate that, when bending your knees during landing, your body moves by about a foot, or 0.30 m. For the purpose of this exercise, you consider yourself with a mass of 60 kg.Given the estimates made above, from how high can you safely jump onto a concrete floor?

In an Atwoods Machine lab with m1 = 0.1 and m2 = 0.13 observed acceleration is 1.20 m/s^2. Compare the value with the a(theoretical). During the momentum collision lab a 2.5kg mass moving with 2m/s hits a stationary 5kg mass. After the collision 2.5kg bounces back with 0.5m/s and 5kg mass moves with 1.2 m/s. Calculate Pi and Pf and compare using percent error. Does this experiment show conservation of momentum?

A 2,800 kg truck jumps the median and clobbers a 940 kg station wagon in a head-on collision. You are tasked with determining the truck's initial speed for insurance purposes. An observer states that the station wagon was traveling at a speed of 25.1 m/s and that after the collision, the two vehicles stuck together and were moving at a speed of 24.4 m/s in the direction the truck was originally moving. What was the truck's original speed?

Assuming that the balls slide on a frictionless surface and all collisions are head-on, find the final speed of the blue ball if the green ball continues moving after the collision at 2.5 m/s in the same direction.
