Determine what is the velocity of the object just then

Reference no: EM13674407

(a) At a certain instant, a particle-like object is acted on by a force F = (2.6 N)i -(3.0 N)j + (5.3 N)k while the object's velocity is v = -(3.4 m/s)i + (5.9 m/s)k. Find the instantaneous rate at which the force does work on the object?

(b) At some other time, the velocity consists of only a y component. If the force is unchanged, and the instantaneous power is -11 W, determine what is the velocity of the object just then?
