1. A 3.0N net force is applied to a 1.5kg mass. What is its acceleration?
(Hint: Neglect the friction)
2. A worker pushes on a crate, which experiences a net force of 75N. If the crate also experiences an acceleration of 0.50 m/s2, what is its mass?
3. A 0.70kg baseball approaches the baseball bat at 20m/s. If it is in contact with the bat at 0.005s, then hits at 30m/s, what is the average contact force between the ball and bat?
(Hint: Acceleration is the change in velocity over time)
