A golf ball is dropped from rest from a height of 9.5m. It hits the pavement then bounces back up rising just 5.7 m before falling back down again. A boy then catches the ball on the way down when it is 1.20 m above the pavement. Ignoring air resistance, calculate the total amount of time the ball is in the air, from drop to catch.

A ball is dropped from rest from the top of the building. What is the velocity of the ball 3.0 seconds after it is released? Answer in meters per second, and use upward as the positive direction.

A ball is dropped from rest from the top of a building. Two motion detectors which are positioned outside of two different windows, one above the other, record the velocities of -15.5 m/s and -17.2 m/s as the ball goes past them. (no air resistance) what is the second motion sensor measure the time it takes for the ball to hit the ground after passing it as 3.50 seconds, how tall is the building?

A golf ball is dropped from rest from a height of 8.10 m. It hits the pavement, then bounces back up, rising just 5.40 m before falling back down again. A boy then catches the ball when it is 1.30 m above the pavement. Ignoring air resistance, calculate the total amount of time that the ball is in the air, from drop to catch.
