Chapter 6, Problem 36PCE
Predict/Explain Suppose m1 and m2 in Example 6-14 (Atwood’s Machine) are both increased by 1 kg. Does the acceleration of the blocks increase, decrease, or stay the same? (b) Choose the best explanation from among the following:
- I. The net force acting on the blocks is the same but the total mass that must be accelerated is greater.
- II. The difference in the masses is the same, and this is what determines the net force on the system.
- III. The force exerted on each block is greater, leading to an increased acceleration.

During a visit to the International Space Station, an astronaut was positioned motionless in the center of the station, out of reach of any solid object on which he could exert a force. Suggest a method by which he could move himself away from this position, and explain the physics involved.
an adventurous archeologist crosses between two rocks cliffs, with a ranging river far below, by slowly going hand over hand along a rope stretched between the cliffs. He stops to rest at the middle of the rope. The rope will break if the tension in it exceeds 3.00 x 10⁴N, and our heros mass is 81.6 kg.
a. if the angle that the rope makes with the cliff is 75°find the tension in the rope.
b. What is the smallest value the angle can have if the rope is not to break?

- A 27.0-kg block is initially at rest on a horizontal surface. A horizontal force of 74.0 N is required to set the block in motion, after which a horizontal force of 61.0 N is required to keep the block moving with constant speed. (a) Find the coefficient of static friction between the block and the surface.(b) Find the coefficient of kinetic friction between the block and the surface.arrow_forwardThe vertical jump height of Michael Jordan (a famous NBA player) is 122cm during his career as a player. His body height is 1.98m. His body weight was 98kg in that same period. Assume that the force his legs act on his body is constant. Also assume that when standing, the height of his center of gravity is half of his body height, and that when he bends his legs at the starting position of jump, his center of gravity decreases to half of the value of standing. (a) Estimate the force that his legs act on the floor, and (b) estimate the duration of the acceleration.arrow_forwardA 10000-kg load sits on the flatbed of a 20000-kg truck moving at 12.0 m/s. Assume that the load is not tied down to the truck, but has a coefficient of static friction of 0.500 and a coefficient of kinetic friction of 0.400 with the flatbed of the truck. If the truck needs to stop in 10.0 m with constant acceleration, what is the force of friction between the load and the truck when the brake is first applied?arrow_forward
- 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.

What is the magnitude of the net force on a 70 kg diver?arrow_forwardA 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.

A record Chinook salmon has a length of 1.50 m and a mass of 61.0 kg. If this fish is moving upward at 3.00 m/s as its head first breaks the surface and has an upward speed of 6.00 m/s after two-thirds of its length has left the surface, assume constant acceleration and determine (a) the salmons acceleration and (b) the magnitude of the force F during this interval.arrow_forwardIn Example 5.7, we pushed on two blocks on a table.
