Question

Can you solve it please

Question 1:

A. A m1 = 80 kg ice skater moving at 50.4 km/h due North crashes into a stationary skater of equal mass. After the collision, the two skaters move as one body at 6 m/s due North. If the collision lasts for 2.0 milliseconds, use the impulse – momentum theorem to find: i. The impulse delivered to the m1 skater due to the collision. ii. The magnitude of the average force exerted on the m1. (1 mark) iii. Suppose the average force a skater can experience without breaking a bone is 4.5x103 N. During this collision, does a bone break? Explain your answer.

B. A boy on a skateboard initially at rest tosses a 7.0 kg jug of water in the West direction. If the jug has a speed of 14.4 km/h and the boy and skateboard move in the opposite direction at 0.80 m/s, in the east direction, use the law of conservation of momentum to find the combined mass of the boy and skateboard.
