A particle is to move in an xy plane, clockwise around the originas seen from the positive side of the z axis. In unit-vectornotation, what torque acts on the particle at time t = 1.6 s if themagnitude of its angular momentum about the origin is (a) 5.9kg·m2/s, (b) 5.9t2 kg·m2/s3, (c) 5.9t1/2 kg·m2/s3/2, and (d) 5.9/t2kg·m2*s?
I know that torque is the time derivative of angular momentum, butam confused about the unit vector notation.
