Answer the following word problems. Follow the procedure shown in the sample problem above.
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) References: Bufa, Anthony J. & Wilson, Jerry D. (2003). College physics. United Kingdom: Pearson Publishing Inc.
