An object acted upon by a force F = (2i + 3j) N is constrained to move along x direction with position vector

Question

An object acted upon by a force \(\vec{F}\)= (\(2\hat{i}+3\hat{j}\))N is constrained to move along x direction with position vector x given by x = (2t² + 3t + 5)im . Calculate the power delivered by the force at t = 2s.

Answer 1

Instantaneous power P . = F v
