An elevator moves downward in a tall building at a constant speed of 5.00 m/s. Exactly 5.00 s after the top of the elevator car passes a bolt loosely attached to the wall of the elevator shaft, the bolt falls from rest, (a) At what time does the bolt hit the top of the still-descending elevator? (b) In what way is this problem similar to Example 2.8? (c) Estimate the highest floor from which the bolt can fall if the elevator reaches the ground floor before the boll hits the top of the elevator.

- Consider a grey squirrel falling from a tree to the ground. Use a coordinate system in which positive is downward for this problem. a) Find the squirrel’s velocity, in meters per second, just before hitting the ground when it falls from a height of 1.3 m. Ignore air resistance. b) The squirrel softens its landing by bending its legs when it touches the ground, thereby stopping itself over a distance of 7.6 cm. Assuming a constant rate of deceleration, find the squirrel’s acceleration during this process, in meters per second squared.arrow_forwardWhile exploring the canopy of the rainforest in equatorial South America, Anastasia falls from a branch 35.0 meters high. Exactly 1.3 seconds later Joe falls from the same branch. How high above the ground is Joe when Anastasia splats into the mud below? (the mud is very squishy and nobody is injured)arrow_forwardA man who is on top of a roof of a high building drops a piece of metallic material. A second piece of metallic material is dropped 3.0 seconds later. How far apart (km) are the materials when the second material has reached a speed of 15.0 m/sarrow_forward
- An attacker at the base of a castle wall 3.65 m high throws a rock straight up with speed 7.40 m/s at a height of 1.55 m above the ground. (a) Will the rock reach the top of the wall? (b) If so, what is the rock’s speed at the top? If not, what initial speed must the rock have to reach the top? (c) Find the change in the speed of a rock thrown straight down from the top of the wall at an initial speed of 7.40 m/s and moving between the same two points. (d) Does the change in speed of the downward-moving rock agree with the magnitude of the speed change of the rock moving upward between the same elevations? Explain physically why or why not.arrow_forwardA student walks off the top of the CN Tower in Toronto, which has height 553 mm and falls freely. His initial velocity is zero. The Rocketeer arrives at the scene a time of 5.50 ss later and dives off the top of the tower to save the student. The Rocketeer leaves the roof with an initial downward speed v0v0. In order both to catch the student and to prevent injury to him, the Rocketeer should catch the student at a sufficiently great height above ground so that the Rocketeer and the student slow down and arrive at the ground with zero velocity. The upward acceleration that accomplishes this is provided by the Rocketeer's jet pack, which he turns on just as he catches the student; before then the Rocketeer is in free fall. To prevent discomfort to the student, the magnitude of the acceleration of the Rocketeer and the student as they move downward together should be no more than five times gg. 1)What is the minimum height above the ground at which the Rocketeer should catch the student?…arrow_forwardA toy rocket moving vertically upward passes by a 1.8 m -high window whose sill is 7.0 m above the ground. The rocket takes 0.16 s to travel the 1.8 m height of the window. a) What was the launch speed of the rocket? Assume the propellant is burned very quickly at blastoff. b) How high will the rocket go?arrow_forward
- You throw two balls directly downwards from a height of 90 m, 3.0 s apart. You throw the first ball at a speed of 8.0 m/s. (a) At what speed must you throw the second ball if it is to reach the ground with the same speed as the first ball? (b) At what speed must you throw the second ball if it is to reach the ground at the same time as the first ball?arrow_forwardA girl standing on a bridge throws a stone vertically downward with an initial velocity of 15.0 m/s into the river below. If the stone hits the water 2.00 seconds later, what is the height of the bridge above the water?arrow_forwardThe basketball bounces straight back up off the ground and reaches a maximum height of 4.00m. a)With what speed did the ball leave the ground? (It is perfectly natural for this to be less than the speed it had before it hit the ground.) The basketball hoop is 3.05 m above the ground. The ball will pass the position of the hoop twice –once on the way up and a second time on the way down. b)Determine the ball's velocity (magnitude and direction) as it reaches the height of the hoop on its way down.arrow_forward
- Two students are on a balcony 19.6 m above the street. One student throws a ball vertically downward at 14.7 m/s; at the same instant, the other student throws a ball vertically upward at the same speed. The second ball just misses the balcony on the way down. What is the difference in the two balls’ time in the air?arrow_forwardA mountain climber stands at the top of a 20.0 m cliff that overhangs a calm pool of water. She throws two stones vertically downward 1.00 s apart and observes that they cause a single splash. The first stone had an initial velocity of -2.20 m/s. (a) How long after release of the first stone did the two stones hit the water? (Round your answer to at least two decimal places.) (b) What initial velocity must the second stone have had, given that they hit the water simultaneously? (c) What was the velocity of each stone at the instant it hit the water?arrow_forwardTwo students are on a balcony 19.6 m above the street. One student throws a ball vertically downward at 14.7 m/s; at the same instant, the other student throws a ball vertically upward at the same speed. The second ball just misses the balcony on the way down. What is the difference in the two balls’ time in the air? (Final answer in seconds and round off to nearest tenths place)arrow_forward
