Chapter 7: Q. 4 (page 176)

How do basketball players jump straight up into the air? Your explanation should include an interaction diagram and a free-body diagram.

Short Answer

Expert verified

The upward normal force owing to the floor, the downward normal force due to gravity, and the downward normal force due to the ball.

Step by step solution

01

Free body diagram

02

Explanation

The player pushes down on the floor.

which in turn pushes him back up.

Because the force of his push is higher than the force of gravity.

The player accelerates upward.

You find yourself in the middle of a frozen lake with a surface so slippery μs=μk=0 you cannot walk. However, you happen to have several rocks in your pocket. The ice is extremely hard. It cannot be chipped, and the rocks slip on it just as much as your feet do. Can you think of a way to get to shore?Use pictures, forces, and Newton's laws to explain your reasoning.

The 1.0kgblock in FIGURE EX7.24is tied to the wall with a rope. It sits on top of the 2.0kgblock. The lower block is pulled to the right with a tension force of 20N. The coefficient of kinetic friction at both the lower and upper surfaces of the 2.0kgblock is μk=0.40

a. What is the tension in the rope attached to the wall?

b. What is the acceleration of the 2.0kgblock?

A long, 1.0kgrope hangs from a support that breaks, causing the rope to fall, if the pull exceeds 40N. A student team has built a 2.0kgrobot “mouse” that runs up and down the rope. What maximum acceleration can the robot have—both magnitude and direction—without the rope falling?

A steel cable lying flat on the floor drags a 20kgblock across a horizontal, frictionless floor. A 100Nforce applied to the cable causes the block to reach a speed of 4m/sin a distance of 2m.

What is the mass of the cable?

A 70 kg tightrope walker stands at the center of a rope. The rope supports are 10 m apart and the rope sags 100 at each end. The tightrope walker crouches down, then leaps straight up with an acceleration of 8.0 m/s2 to catch a passing trapeze. What is the tension in the rope as he jumps?
