A 2000kg car is traveling at 15m/s. If a force of 120N is applied to the car in the same direction it is already moving for 5 seconds, what will its final velocity be?

What is the weight of a feather (mass = 0.0001 kg) that floats through earth's and the moon's atmospheres?

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.
