25 points! 1.) Equally massive cars collide, where one was stationary and the other was moving to the right. What is the end result of this collision and explain how you know this
2.) If a clay ball of a mass 1.5 kg moving at speed 6 m/s to the right, collides and sticks to a stationary ball of mass 4 kg what is the end movement of the new mass.

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
