A rock is thrown straight up and passes by a window. The window is 1.7m tall, and the rock takes 0.19 seconds to pass from the bottom of the window to the top. How far above the top of the window will the rock rise?
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 0.12 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...
1. Recall the following scenario from a class activity: A ba is thrown (from the ground) to a height of 10 feet. It then falls and bounces repeatedly. After each bounce, it rises to of the previous height (a) Express the total vertical distance the ball travels until it stops (going up and down on each bounce) as a geometric series and compute its value using the short-cut formula for geometric series. Make sure to justify the geometric series you...
A ball is thrown straight up with an initial speed of v m/s. The ball was released 1.2 m above the ground, but when it returns back down, it falls into a hole 14.2 m deep. If the ball’s speed at the bottom of the hole is 28 m/s, what was the initial speed v (in m/s) of the ball?
A ball is thrown straight up into the air from the ground with initial velocity v0= 4 m/s, it reaches its apex and falls back down. Neglecting air resistance, how long does it take the ball to return to the ground?
a ball up. The ball rises to a height and falls back down so that the person catches it. When is the acceleration of the ball at its 3 just before the person catches it 1.66 from the top of a tall building with an initial veloc Select Jane up be the positive direction. What is the initial velocity of the rock? is riding in a hot air balloon that is rising vertically at a constant speed of 3 m/s...
An experiment to measure the value of g is constructed using a tall tower outfited with two sensing devices, one a distance H above the other. A small ball is fired straight up in the tower so that it rises to near the top and then falls back down; each sensing device reads out the time that elapses between the ball going up past the sensor and back down past the sensor. 1) Choose an expression for g using times...
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 ...
Please answer the following physic questions. Thank you! 1. A dog sees a flowerpot sail up and then back past a window 5.0 ft high. If the total time the pot is in sight is 1.0 seconds, find the height above the window that the pot rises. 2. An elevator ascends with an upward acceleration of 4.0 ft/s2. At the instant its upward speed is 8.0 ft/s, a loose bolt drops from the ceiling of the elevator 9.0 ft from...
