What is the angle between the force and the displacement

Reference no: EM13646687

A 12.0 N force with a fixed orientation does work on a particle as the particle moves through displacement d= (2.00i - 4.00j + 3.00k) m. What is the angle between the force and the displacement if the change in the particle's kinetic energy is

(a) +30.0 J and

(b) -30.0 J?
