Question

2 kg of mass is placed on x axis 2m away from the origin, the particle is released from rest to fall under the effect of gravity. Calculate the angular momentum and torque

Answer 1

At $t=0$ the angular momentum is $L=0$.

Torque $\tau=r\cdot F=r\cdot mg=2\cdot2\cdot9.81=39.24\ (N\cdot m)$ .
