In a collision experiment, the ratio of the velocity change between two carts of equal inertia is found to equal 1. What happens to this ratio if the experiment is repeated in the following conditions? (a) The inertia of each cart is doubled, and the same initial velocities are used. (b) The original value of inertia is used, and the initial velocities of the carts are doubled.

We did an experiment with newtons third law where we pushed two carts together and measured the force exerted with a computer. We did it with springs in between the carts first, which showed the force of the carts to be equal. Then we did it with clay attached to collision ends of the carts and the computer read more force on cart A than cart B. Why? Then.... when they had opposite magnets on and we pushed then together there was also more force read on cart A than cart B. Why? With both scenerios we also had cart B be still and we pushed cart A into it. They exerted the same force? Was there human error in this experiment or is there an explanation for it?

Two carts a & b are at rest back to back, one is springloaded with its spring resting on the other cart. When spring isreleased carts move in opposite directions. If Ea and Eb are thekinetic energies of the two carts after the spring is released,prove that the ratio Ea/Eb is equal to the ratio mb/ma

s in procedure 1: a pair of carts sit on a frictionless track.Assume the mass of the larger cart is 4.2 times the mass of thesmall cart, In this system, however, there is a spring between thecarts which can "explode", pushing on the two carts at once..
NOTE: Every velocity needs magnitude and direction (given by thesign).

a) Suppose the carts are initially at rest, and after the"explosion" the smaller cart is moving at velocity +6.45 m/s.
- Find the velocity of the larger cart. m/s
- If the mass of the smaller cart is 7.96 kg, find the energysupplied by the spring to the carts. J
- If the spring has spring constant k = 971 N/m, find the distancethe spring was compressed before the "explosion". m
HINT: Think conservation of energy!

b) Suppose the carts are initially moving together at constantvelocity +3.96 m/s. After the "explosion", the smaller cart ismoving at velocity +6.45 m/s. Find the velocity of the largercart.
