While sliding across a horizontal surface (with a uniform coefficient of friction across the entire surface), a hockey puck slows down due to friction, and comes to rest after 20.0 s.
a) Find how does the change in energy in the first 10 sec compare to the change in energy in the last 10 sec?
b) If the puck has a mass of 170 gram, an initial velocity of 47m/s and the coefficient of friction is .2398, evaluate the change in kinetic energy during the first 10 sec and compare it with the change in kinetic energy in the last 10 sec.
