A pebble is thrown horizontally at a speed of 5.0 m/s from the top of a condominium 78.4 m high. How long does it take the pebble to reach the ground? 1. a. How far from the base of the condominium does the pebble hit the ground? b. с. What are the horizontal and vertical components of the pebble's velocity just before it hits the ground?

A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 8.8m/s at an angle of 23 degrees SE from the window (downwards, not upwards). It hits the ground 5s later. a. How far horizontally from the building does the ball land on the ground? b. Find the height that the ball was thrown from

A ball is thrown horizontally from a cliff of height 90 meters with an initial speed of 45 m/s. A. How far from the base of the cliff will it strike the ground? B. What is its vertical component of velocity when it strikes the ground? C. What is its speed when it strikes the ground?

24. A rocket is fired upward on a straight upward trajectory at 90 degrees to the surface perfectly, starting from rest with an acceleration of +29.4 m/s² for the first 4 seconds of travel. After finishing these 4 seconds it runs out of gas but continues its upward movement on its original path for a short time. a. b. What is the maximum height it reaches? If after reaching the maximum height it is allowed to fall in free fall in a perfectly linear path towards the earth, what is its final speed just before hitting the ground? Select one: - b. a. Maximum height = 135.8 meters, final velocity = 940.8 meters/seconds Maximum height = 940.8 centimeters, final velocity = 135.8 centimeters/seconds c. Maximum height = 940.8 centimeters, final velocity = 13.58 meters/seconds d. Maximum height = 940.8 meters, final velocity = 135.8 meters/seconds
