A particle of mass 110 kg is moving with velocity v 76i59jms

A particle of mass 1.10 kg is moving with velocity v =(7.6i^+5.9j^)m/s. At position r a force of F =4.0Ni^ is applied to the particle. Find the torque relative to the origin.

Solution

Torque = RxF

T = (2.7j +4.6 k)X 4 i

T = -10.8 k -18.4 j

T = -18.4 j -10.8 k Nm
