A ball is dropped out of a window and falls for 8.75 s. What is the...
A ball is thrown straight up. It passes a 2.00-m-high window 7.50 m off the ground on its path up and takes 0.312 s to go past the window. What was the ball's initial velocity? Next, consider only the distance from the ground to the bottom of the window, and solve for the initial velocity using the velocity at the bottom of the window as the final velocity.
A steel ball is dropped from a building's roof and passes a window, taking 0.210 s to fall from the top to the bottom of the window, a distance of 1.80 m. It falls to a sidewalk and bounces back pass the window, moving from bottom to top in 0.210 s. Assume that the upward flight is an exact reverse of the fall. The time the ball spends below the bottom of the window is 3.00s. a) How tall is...
A steel ball is dropped from a building's roof and passes a window, taking 0.12 s to fall from the top to the bottom of the window, a distance of 1.20 m. It then falls to a sidewalk and bounces back past the window, moving from bottom to top in 0.12 s. Assume that the upward flight is an exact reverse of the fall. The time the ball spends below the bottom of the window is 1.74 s. How tall...
A 0.659-kg basketball is dropped out of a window that is 5.28 m above the ground. The ball is caught by a person whose hands are 1.50 m above the ground. (a) How much work is done on the ball by its weight? What is the gravitational potential energy of the basketball, relative to the ground, when it is (b) released and (c) caught? (d) What is the change (PEf - PE0) in the ball's gravitational potential energy?
A 0.636-kg basketball is dropped out of a window that is 6.34 m above the ground. The ball is caught by a person whose hands are 2.05 m above the ground. (a) How much work is done on the ball by its weight? What is the gravitational potential energy of the basketball, relative to the ground, when it is (b) released and (c) caught? (d) What is the change (PEf - PE0) in the ball's gravitational potential energy
please show work! 9. A 2-kg ball is dropped out of a w is dropped out of a window from a height of 12 meters (Point A). It hits the grow and bounces back up to a height of 8 meters above the ground (Point). a. What is the potential energy of the ball at points A and C b. What is the velocity of the ball just before and just after it hits the ground (points B and B')?...
A boy reaches out of a window and tosses a ball straight up with aspeed of 10 m/s. The ball is 20 m above the ground as he releasesit. Use energy to find a.The ball's maximum height above the ground. b.The ball's speed as it passes the window on its waydown. c.The speed of impact on the ground.
A ball is dropped in front of a window that is 1.5m tall. It takes 0.2 seconds for the ball to pass the window. What is the initial velocity at the top of the window?

A boy reaches out of a window and tosses a ball straight up with a speed of 10 m/s. The ball is 20 m above the ground as he releases it. Use conversation of energy to find Part A The ball's maximum height above the ground. Express your answer using two significant figures. hmax = m Part B The ball's speed as it passes the window on its way down. Express your answer using two significant figures. vwindow = m/s ...
