Instead of doing his work, georges throws a textbook at devine. after just 0.2 s, it is moving at 10.4 m/s. find its acceleration.

To travel at constant speed, a car engine provides 24kw of useful power. the driving force on the car is 600n. at what speed does it travel?

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.

The voltage applied across a given parallel-plate capacitor is doubled. how is the energy stored in the capacitor affected?
