Ignoring air resistance, how fast would a box hit the ground if dropped from 28.9 m?
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?
A pair of glasses are dropped from the top of a 32.0 m high stadium. A pen is dropped from the same position 2.00 s later. How long does it take for the glasses to hit the ground? How high above the ground is the pen when the glasses hit the ground? (Disregard air resistance)
A ball is dropped from a rocket that is 350 m above the ground and rising at 18 m/s. ( We choose the origin to be at ground level and neglect the air resistance.) (a) What is the maximum height that the ball reached? (b) What are the position and the velocity of the ball after being released for 4s? (c) What is the total time the ball taken to hit the ground?
7 pts Question 12 If there were no air resistance, a penny dropped from the top of a skyscraper would reach the ground 9.8 s later. To the nearest integer, what would the penny's speed in m/s be right as it reaches the ground if it was dropped from rest?
A coin is dropped from a hot air ballon that is 310 m above the ground + rising vertically at 9.5 m/s. For this problem use a coordinate system in which up is positive. a.) Find the maximum height in meters, that the coin attains. b.) Find the height above the ground, in meters, 4.00 s after being released. c.) Find its velocity, in meters per second, 4.00 s after being released. d.) Find the time, in seconds, that it...
(Assume there is no air resistance.) A ball of mass m and another ball of mass 3m are dropped. The two balls have the same kinetic energy when they hit the ground. If the ball of mass m was dropped from height h, the height of the ball of mass 3m dropped is h/3. Explain why.
A ball is dropped from rest and takes 1.3 s to hit the ground. From what height was it dropped? A. 7.5 m B. 8.3 m C. 13 m D. 17 m
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 window which is 27.87 m above the ground, how much time did it take the ball to hit the ground?
Answer the following questions: a. How long would it take for an object dropped from the Leaning tower of Pisa (height 54.6 meters) to hit the ground? b. How fast was the object travelling at the moment of impact?
