Answer the Questions:

1. Which has greater inertia: a pickup truck (1000 kg) or a motorcycle (250 kg)? Why?

2. If the frequency of a pendulum is decreased by a factor of 3, what will happen to the period of the pendulum? If frequency decreases, then period will increase. Specifically, the period will increase by a factor of 3.

3. What is the acceleration of a mouse that starts at rest and reaches a maximum speed of 2 meters/second in 4 seconds?

4. A projectile is fired at an angle of 45 degrees and an initial velocity of 35 m/s. How long does the projectile remain in the air? Assume initial and final heights are both zero.

5. Using your answer from #4, how far does the projectile travel?

6. A tennis ball is dropped from the top of a building on Earth. It takes 4 seconds to reach the ground (assuming no air resistance). How far did the tennis ball fall? Initial velocity is zero!

Assume g = 9.8 m/s²
