A skydiver jumps out of a helicopter and falls freely for 7.2 s before opening the parachute. (a) What is the skydiver's downward velocity when the parachute opens?   m/s (b) How far below the helicopter is the skydiver when the parachute opens?   m

A test rocket is launched by accelerating it along a 200.0m incline at 1.85m/s2 starting from rest at point A. The incline rises at 35.0o above the horizontal, and at the instant the rocket leaves it, it's engines turn off, and it is subject only to gravity (air resistance can be ignored) a) find the maximum height above the ground that the rocket reaches in m b) find the greatest horizontal range of the rocketbeyond point A

You throw a small rock straight up from the edge of a highway bridge that crosses a river. The rock passes you on its way down, 8.00 s after it was thrown. What is the speed of the rock just before it reaches the water 29.0 m below the point where the rock left your hand? Ignore air resistance

Problem 5: A ball is thrown horizontally from the top of a 70 m building and it lands 90 m from the base of the building. a) How long is the ball in the air? b) What must have been the initial speed of the ball? c) What is the vertical component of the ball's velocity just before it hits the ground? d) What is the ball's speed just before it hits the ground?

6. A stunt man drives a car at a speed of 20 m/sec off a ramp that is 30 m above the ground. The ramp leading up to the take-off point is inclined at 20°. a) What is the time for the upward part of the motion only? b) What is the maximum height of the car relative to the ground? c) How far from the base of the cliff does the car land?
