Question Translation:
On a car of mass M, two forces act as shown in the figure
above. Find an expression for the acceleration of the car in terms
of T, F, and M. What happens to the acceleration if we double the
mass of the car?
An object of mass M is in free fall (the only force on the
object is its weight). Make a force diagram for this case. Use
Newton's second law to calculate the acceleration of...

ABC bar has a mass of 2.87kg and is attached to a B-bracket bolt. A 0.65kg D-sphere hits the end of the bar with a vertical velocity v1 of 3.32m / s. If L = 0.73m and the coefficient of restitution between the sphere and the bar is 0.49, determine the angular velocity, in rad / s, of the bar immediately after impact.
