In a new experiment, a spring is attached to the right end of cart A. Cart B is at rest between the photogates when cart A is given an initial speed to the right, passes through photogate X, and collides with cart B. The speed of each cart before and after the collision is measured. It is discovered that the sum of the kinetic energies of the two carts after the collision is about 5% greater than the kinetic energy of cart A before the collision. Which of the following is the best explanation for the difference in the kinetic energy
a. The scale used to determine the masses of the carts is off by 5%
b. During the collision, some of the kinetic energy of the carts is converted to heat.
c. Some of the elastic potential energy of the spring Is converted to kinetic envoy
d. There is a small amount of friction between the track and the sous
e. One end of the track is slightly higher than the other

One hazard of space travel is debris left by previous missions. there are several thousand masses large enough to detect by radar orbiting the earth, but there are far greater numbers of very small masses such as flakes of paint. calculate the force exerted by a 0.110 mg chip of paint that strikes a space shuttle window at a relative speed of 5.00 ✕ 103 m/s and sticks, given the collision lasts 6.00 ✕ 10-8 s. such a collision chipped the window of the ill-fated challenger in june 1983, causing $50,000 of damage.
