A 170 gram ball is dropped from rest off of a cliff. the ball then drops straight down to the ground, 19m below. if the speed of the ball just before it hits the ground is 8 m/s, how much work is done to the ball by the fore of air resistance as it falls?

A golf ball is dropped from rest from a height of 8.10 m. It hits the pavement, then bounces back up, rising just 6.10 m before falling back down again. A boy then catches the ball when it is 1.50 m above the pavement. Ignoring air resistance, calculate the total amount of time that the ball is in the air, from drop to catch.

A cannon shoots a cannonball from the ground level (ignore the height of the cannon) towards a cliff of height h = 170 m
A cannon shoots a cannonball from the ground level (ignore the height of the cannon) towards a cliff of height h = 170 m. The cannonball is launched with an initial velocity of 110 m/s at an angle of 64° above the horizontal. Neglect air resistance. Assume the cannonball hits the cliff as it descends (on its way down) exactly at the edge, as shown. a. Determine the maximum height above the ground reached by the cannonball.b. What speed will the...

A 290 g ball is initially at rest has fallen off of a 15 m high cliff. Assume the base of the cliff is where y = 0 m. Calculate the gravitational potential energy. What is the kinetic energy of the ball right before it hits the ground? Calculate the speed of the ball right before it hits the ground.
