A potter's wheel of radius 0.50 m and mass 100.0 kg is freely rotating at 5.2 rad/s. The potter can stop the wheel in 6.0 s by pressing a wet rag against the rim. To find moment of inertia, use I=\frac{mr^2}{2}I = m r 2 2 a. What is the angular acceleration of the wheel?

b. How much torque does the potter apply to the wheel?

What best describes a sonar wave? transverse and electromagnetic transverse and mechanical longitudinal and electromagnetic longitudinal and mechanical

Aboxcar traveling at 12 m/s approaches a string of 5 identical boxcars sitting stationary on the track. the moving boxcar collides and links with the stationary cars and they all move off together along the track. what is the final speed of the cars immediately after the collision? (you may take the mass of each boxcar to be 18,537 kg.)

The velocity of car is 80.0 miles per hour. what is the velocity of car in meters per second? (1 km -0.621 miles) m/s
