Question: Your physics textbook is sliding to the right across the table. Part A Identify all forces acting on the object and draw a free-body diagram. Draw the vectors starting at the black dot. The location and orientation of the vectors will be graded. The exact length of your vectors will not be graded but the relative length of one to the other will be graded.
What is the final velocity of a hoop that rolls without slipping down a 7.50 m high hill, starting from rest
A woman in a movie fires a gun and is pushed backwards. The mass of the bullet is 0.050 kg and the bullet velocity is +850 m/s. What is the recoil velocity of the woman

At t = 0, a wheel rotating about a fixed axis at a constant angular acceleration of -0.40 rad/s^2 has an angular velocity of 1.5 rad/s, What is the angular position of the wheel at t = 2.0 s
The two blocks (m = 30 kg and M = 100 kg) in the figure below are not attached to each other. The coefficient of static friction between the blocks is µs = 0.49, but the surface beneath the larger block is frictionless.
One cylinder in the diesel engine of a truck has an initial volume of 700 cm3. Air is admitted to the cylinder at 35 deg C and a pressure of 1.0 atm. The piston rod then does350 J of work to rapidly compress the air.
