The position vector of a particle is given by r = 8ti + 1.2t 2 j
Question:
The position vector of a particle is given by r = 8ti + 1.2t2j − 0.5(t3 − 1)k, where t is the time in seconds from the start of the motion and where r is expressed in meters. For the condition when t = 4 s, determine the power P developed by the force F = 40i − 20j − 36k N which acts on the particle.
