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) a. How far apart are the motion sensors mounted? b. How far from the top motion sensor is the top of the building where the ball was released? c. If the second motion sensor can...
An object, at the top of a very tall building, is released from rest and falls freely due to gravity. Neglect air resistance and calculate the distance covered by the object between times t1 = 4.12 s and t2 = 6.27 s after it is released.
A ball is dropped from the top of a building 100 m high. (Ignore air resistance) a) How long does it take the ball to hit the ground? b) What is the speed of the ball when it hits the ground?

4. An object is released from rest from the top of a tall building. Use g 9.8 m/sec?. Ignore air resistance. a) What is the speed of the object 1 second after it is released? 3 seconds after it is released? b) The building is 100 m tall. How many seconds will it take for the object to reach the ground? c) What is the speed of the object just...
2) A little stone is released from an air-balloon that was flying horizontally in the skies. The stone stayed in the air for a period of time of 3 s and hit the ground at an angle of 30° with respect to a vertical line. a) From what height was the rock released from the balloon? b) What was the magnitude of the balloon velocity? c) What was magnitude of the velocity when the rock hit the ground?
2) A...
Imagine a piece of clay putty being dropped from a tall building. Neglecting air-resistance, describe the mechanical energy of the system as the putty falls to the ground and also mention where the initial energy comes from. After the putty collides with the ground it flattens and sticks to the ground. What happens to the mechanical energy of the system? Explain.
2-N stone is dropped from the top of a cliff. The stone hits the ground 3 seconds later. N stone is dropped from the top of a cliff. The stone hits the ground 3 seconds later. The height of the cliff is approximate? The Speed of the stone is?
In order to defeat Bowser, suppose Mario launched a stone from his sling with an initial velocity of 30.5 m/s at an angle θ=20 degrees above the horizontal. The stone flies through the air and strikes Bowser between the eyes exactly 2.00 seconds after it was released. Assume Mario and Bowser are standing on flat ground, and the stone strikes Bowser on its way back down (after reaching its maximum height). You may neglect air resistance. A) how far away...
