a 200g rubber ball traveling with a momentum of 20.0 kg x m/seast rebounds off the wall with a momentum of 18.0 kg x m/s west.The ball is in contact with the wall for 0.100s
1. The force that the wall exerts on the ball during thecollision is
a)380 N west
b) 380 N east
c)20 N west
d)20 N east
2. during the collision above, how much kinetic energy is lostby the ball?
a)10.0J
b)3.61 x 10^3J
C) 190J
d)20J
3. Kinetic energy lost from the system above was not actuallylost. Rather it was converted into
a) sound energy and heat due to friction
b) heat due to friction only
c)heat due to air resistance only
d)sound and heat due to air resistance
