Given that the collision is completely inelastic and glider 2 is initially at rest = 0), show that the energy loss rate always satisfies |+−−| |+| = m2 m1+m2 (hint: find the kinetic energies in terms of and use them to compute the loss rate). explain how this relation tells that the energy is not conserved upon a completely inelastic collision

An object resting on a table weighs 100 n. with what force is the object pushing on the table? with what force is the table pushing on the object? explain how you got your answer.

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:

You hang a book bag on a spring scale and place the bag on a platform scale so that the platform scale reads 23.7n and the spring scale reads 13.8n. what is the magnitude of the force that earth exerts on the bag?
