Chapter 5, Problem 55GP
** A Tarzan swing Tarzan (mass 80 kg) swings at the end of an 8.0-m-long vine (Figure P5.55). When directly under the vine's support, he releases the vine and flies across a swamp. When he releases the vine, he is 5.0 m above the swamp and 10.0 m horizontally from the other side. Determine the force the vine exerts on him at the instant before he lets go (the vine is straight down when he lets go).

A new Dutchman Day activity allows people to leap from the top of the Humanities building onto a giant pillow on the ground below. The distance between the top of the Humanities building and the top of the pillow is 9.34 m. The giant pillow compresses 0.781 m as it brings a 60.7-kg person to rest. Find the magnitude of the force (in N) exerted by the giant pillow on the person. You may assume this force is constant during the time that the person is in contact with the pillow.
A new Dutchman Day activity allows people to leap from the top of the Humanities building onto a giant pillow on the ground below. The distance between the top of the Humanities building and the top of the pillow is 9.67 m. The giant pillow compresses 1.14 m as it brings a 66.8-kg person to rest. Find the magnitude of the force (in N) exerted by the giant pillow on the person. You may assume this force is constant during the time that the person is in contact with the pillow. (Hints: Draw a free body diagram for a person in the air, after leaving the top of the Humanities building, before hitting the giant pillow. Indicate all of the vertical forces that act on the person. You may ignore air resistance. Find out the velocity of the person just before he hits the pillow. Then, draw a free body diagram for a person in contact with the giant pillow. Indicate all of the vertical forces that act on the person. You may again ignore air resistance.)

Starting from rest, a 65.0-kg athlete jumps down onto the platform from a height of 0.600 m. While she is in contact with the platform during the time interval 0t 0.800 s, the force she exerts on it is described by the function F = 9 200t 11 500 t2 where F is in newtons and t is in seconds. (a) What impulse did the athlete receive from the platform? (b) With what speed did she reach the platform? (c) With what speed did she leave it? (d) To what height did she jump upon leaving the platform?arrow_forwardReview. A magician pulls a tablecloth from under a 200-g mug located 30.0 cm from the edge of the cloth.

Assume that the driver begins to brake the car when the distance to the wall is d=109 m, and take the car's mass as m=1430 kg, its initial speed as v0=39.0 m/s, and the coefficient of static friction as μS=0.500.
