In Fig. 7, a cumin canister of mass n 0.40 kg/slides across a horizontal frictionless counter with speed v = 0.50 m/s. It then runs into and compresses a spring of spring con- stant k = 750 N/m. When the canister is momentarily stopped by the spring, by what distance d is the spring Compressed?​

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.

Since the energy was not raising the temperature of the water during these segments, what was the energy used to do instead? your answer must include an explanation of what is happening to the molecules.
