At a certain instant, a particle-like object is acted on by a force F = (4.0 N) - (2.0 N) + (9.0 N) while the object's velocity is v = - (2.0 m/s) + (4.0 m/s) . What is the instantaneous rate at which the force does work on the object? At some other time, the velocity ...
Tarzan, who weighs 880 N, swings from a cliff at the end of a 38.0 m vine that hangs from a high tree limb and initially makes an angle of 43.0° with the vertical. Assume that an x axis extends horizontally away from the cliff edge and a y axis extends upward. Immediately ...
