Determine the momentum of a tortoise with a mass of 30 kg moving at a velocity of 0.5 m/s. Question 20 options: 45 kgm/s 60 kgm/s 15 kgm/s 75 kgm/s

A Roger Federer (65kg) is in position to hit a ball served to him. The 0.060-kg tennis ball comes towards Federer at 12 m/s [fwd]. He strikes the ball and returns it at a speed of 18 m/s [bwd]. What is the magnitude of the ball's change in momentum? a) 0.36 kg-m/s b) 0.72 kg-m/s 390 kg-m/s d) 1.8 kg-m/s

Ball C has a mass of 0.5Kg. Ball D has a mass of 1.0Kg. Ball C is moving at 6.0m/s and collides head in with Ball D that is moving in the opposite direction at 12m/s. Ball C bounces back at 14m/s after the collision. What is the velocity of ball D after the collision?

A 0.145 kg ball is thrown horizontally into a wall, to the right, with an initial velocity of 8.0 m/s and bounces in the opposite direction with a velocity of 5.0 m/s. Find the change in momentum of the ball. -2.78 kg m/s O-1.90 kg m/s 1.90 kg m/s 0.44 kg m/s
