Chapter 7: Q. 2 (page 176)

How does a sprinter sprint? What is the forward force on a sprinter as she accelerates? Where does that force come from? Your explanation should include an interaction diagram and a free-body diagram.

Short Answer

Expert verified

The interaction diagram and free body diagram is given below.
The system consist of both weight lifter and the bar bell together.

Step by step solution

01

Step 1:Weightfilter

The preceding are the initiative couples of just a weightlifter making a stand out of a seated position with a massive hammer atop his neck.

The lower block in FIGURE CP7.53 is pulled on by a rope with a tension force of 20 N. The coefficient of kinetic friction between the lower block and the surface is 0.30. The coefficient of kinetic friction between the lower block and the upper block is also 0.30.

What is the acceleration of the 2.0 kg block?

A 3200kghelicopter is flying horizontally. A 250kgcrate is suspended from the helicopter by a massless cable that is constantly 20掳from vertical. What propulsion force F u prop is being provided by the helicopter鈥檚 rotor? Air resistance can be ignored. Give your answer in component form in a coordinate system where i^points in the direction of motion and j^points upward.

The century-old ascensores in Valparaiso, Chile, are picturesque cable cars built on stilts to keep the passenger compartments level as they go up and down the steep hillsides. As FIGURE P7.43shows, one car ascends as the other descends. The cars use a two-cable arrangement to compensate for friction; one cable passing around a large pulley connects the cars, the second is pulled by a small motor. Suppose the mass of both cars (with passengers) is 1500kg, the coefficient of rolling friction is 0.020, and the cars move at constant speed. What is the tension in (a) the connecting cable and (b) the cable to the motor?

A Federation starship 2.0脳106kguses its tractor beam to pull a shuttlecraft 2.0脳104kgaboard from a distance of 10km away. The tractor beam exerts a constant force of 4.0脳104N on the shuttlecraft. Both spacecraft are initially at rest. How far does the starship move as it pulls the shuttlecraft aboard?

A 40cmdiameter, 50cmtall, 15kghollow cylinder is placed on top of a 40cm-diameter, 30cm-tall, 100kgcylinder of solid aluminum, then the two are sent sliding across frictionless ice. The static and kinetic coefficients of friction between the cylinders are 0.45and 0.25, respectively. Air resistance cannot be neglected. What is the maximum speed the cylinders can have without the top cylinder sliding off?
