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 40g body falls, from rest, through a vertical distance of 25 cm to the ground. What is the kinetic energy and the velocity of the body just before hitting the ground?
A cylinder is dropped from rest at a height of 3.71 m above the ground. How long after it is release does the cylinder reach the ground (in seconds)? What is the instantaneous velocity of the cylinder just before it hits the ground (in m/s)?
An object is dropped from rest of 35 m above the ground. A how long will it take for the object to hit the ground B What is th magnitude of the velocity just prior to hitting the ground
A ball is dropped from a building 110m high and hits the ground. What was its final velocity in m/s just as it hit the ground
(a) A ball is dropped from rest from an initial height h above the floor. It then bounces several times. Draw graphs the position y(e), velocity v, (e) and acceleration ay () of the ball for two complete bounces (hitting the ground t for py Ct) ay (t) (b) If the ball is released from rest at a height h the ground? 1.50 m above the floor, how fast is the ball moving when it reach (c) If the ball...
5. A ball is dropped from rest from the top of a building of height h 100.25 m friction, find (a) How long does it take the ball to hit the ground? (b) What speed (b) What speed does the ball travel the instant before it hits the ground?
A ball thrown horizontally at 25 m/s travels a horizontal distance of 50 m before hitting the ground. Part A From what height was the ball thrown? Express your answer in meters. Part B If instead it was launched at an angle of 25 degrees above the horizontal at a velocity of 25 m/s , how high would it go? Express your answer in meters.
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 ball is shot from the ground into the air. At a height of 9.80 m, its velocity is v = (8.50i + 4.00j) m/s, with i horizontal and j upward. To what maximum height does the ball rise? What total horizontal distance does the ball travel? What is the magnitude of the ball's velocity just before it hits the ground? What is the angle (below the horizontal) of the ball's velocity just before it hits the ground?
