A body constrained to move along z axis

Asked by admin @ 27/08/2021 in Physics viewed by 299 People

A body constrained to move along z axis under a constant force F=-i^+2j^+3k^ N. Work done by this force in moving the body a distance 4m along the z axis

Answered by admin @ 27/08/2021

Work done =F × displacememt
work done in z axis =3×4
12
so work done in z axis is 12 Nm
