Answer #1

Torque is produced when there is presence of unbalanced force. Let's look into options one by one:

a) Gravitational force: Gravitational force is balanced by normal reaction force of the car, therefore it is not responsible for slight rotation. Moreover, gravitational force on an object is just the weight.

Therefore option a), c), and d) are incorrect.

b) Frictional force: As the center of mass is somewhere in the center of the car, therefore when car suddenly stops the friction force which is acting opposite to the direction of motion will make the car rotate slightly.

Therefore the correct answer is option .

You are driving down IL-53 at 45 miles per hour in your 1325 kg car. As you look down to check a text, a car 75 m in front of you stops. It takes you 2.0 s to look at the text, realize there’s a stopped car in front of you, and hit the brakes. Your car skids along the concrete (µk=0.8 between rubber and dry concrete) and slows. (a) How far does your car travel in those 2.0 s...

The combination of an applied force and a frictional force produces a constant torque of 40 N·m on a wheel rotating about a fixed axis. The applied force acts for 8.0 seconds, during which time the angular speed of the wheel increases from 0 to 700 degrees/second. The applied force is then removed, and the wheel comes to rest in 55 s. Answer the following questions. (a)What is the magnitude of the angular acceleration of the wheel while the applied...
