1. Discover the magnitude of the linear momentum of a 1200 kg automobile traveling at 50km/h.
2. A 2.4kg mud ball drops from rest at a height of 13m. If the impact among the ball and the ground lasts 0.30s, what is the average net force exerted by the ball on the ground?
3. A 0.50 kg volleyball travels with a horizontal velocity of 5.0m/s over the net. You jump up and hit the ball back with a horizontal velocity of 8.0m/s. If the contact time is 0.030s, what was the magnitude of the average force on the ball?
