Question

1. Two identical eggs were thrown at the same time from the top of a building of height 100 m at a speed 20. One egg was thrown at an angle 40° above the horizontal while another was thrown at the same angle but below the horizontal. How long does it take for the other egg to hit the ground after the one of the eggs hits the ground?

Does the time difference between the eggs hitting the ground depend on the height of the building?

Assume air resistance is negligible.

2. A 19 cannonball is dropped from the top of a 130 m building. The cannonball experiences an average frictional force of 6 N as it falls. What is the speed of the cannonball when it hits the ground?

3. A cannonball is fired from the top of a hill of height 100 m at a speed 120 and at an angle 40° above the horizontal. Determine the horizontal distance traveled by the cannonball before it hits the ground (0 m).

Assume air resistance is negligible.
