A stationary golf ball and tennis ball rest on two separate golf trees. A golfer applies an equal Impulse to both balls using a golf club which of the following statement is true A) both balls will have the same momentum but different velocities
B) The force is applied to both balls is equal
C) both balls will have the same velocity but different momenta
D) both balls will have the same acceleration

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
