You board a stationary elevator on the ground floor. A uniform vertical gravitational field g = −9.8m/s2 is present. Before the elevator starts moving, you drop a ball from a height of 2 m above the floor. a) How long does it take for the ball to reach the floor of the elevator? b) How long does it take for the ball to travel from the floor to its maximum height above the floor (at which point you catch it...
6.While riding on an elevator descending at a constant speed of 4.35 m/s, you accidentally drop a book from under your arm (1.25m above the elevator floor) how long does it take for the book to hit the floor?
John’s car is 0.50 mile behind Allen’s car while John is moving at 70 mile/hour and Allen 60 mile/hour. a) If John doesn’t accelerate, how long does take him to catch up (right next to) with Allen? b) If John would like to catch up with Allen in 10 second, what kind of acceleration that John needs to get from his car? At the moment when John’s car catches up with Allen’s, how far has John traveled from...
A ball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. If the ball hits the floor with a speed of 2.30 m/s and rebounds with a speed of 2.00 m/s, determine the following. (a)magnitude of the change in the ball's momentum in kg · m/s (Let up be in the positive direction.) kg · m/s (b)change in the magnitude of the ball's momentum in kg · m/s (Let negative values indicate a...
Plzzzz answer and show all work for the questions below. including all free body diagrams. III. An elevator is moving upward at a ceiling 2.50 m above the floor of t 15. How long does it take at a constant speed of 4.00 m/s. A bolt in the elevator the floor of the elevator works itself loose and falls to the floor. long does it take for the bolt to fall to the elevator floor? a. 0.422 s b. 0.851...
You are moving into an apartment and take the elevator to the 6th floor. Suppose your weight is 730 N and that of your belongings is 980 N. (a) Determine the work done by the elevator in lifting you and your belongings up to the 6th floor (15.2 m) at a constant velocity. (b) How much work does the elevator do on you alone (without belongings) on the downward trip, which is also made at a constant velocity?
A ball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. If the ball hits the floor with a speed of 3.30 m/s and rebounds with a speed of 1.50 m/s, determine the following. (a) magnitude of the change in the ball's momentum in kg · m/s (Let up be in the positive direction.) (b) change in the magnitude of the ball's momentum in kg · m/s (Let negative values indicate a decrease...
A 3.00 kg ball is dropped from the roof of a building 176.4 m high. While the ball is falling to Earth, a horizontal wind exerts a constant force of 12.0 N on it. a.)How far from the building does the ball hit the ground? b.)How long does it take to hit the ground? c.)What is its speed when it hits the ground?
A ball is dropped from 1.524 m and hits the floor with impact speed. Use conservation of energy to calculate the ball's speed when it hits the ground, the impact speed.
