Suppose you start an antique car by exerting a force of 258 n on its crank for 0.270 s. what angular momentum is given to the engine if the handle of the crank?

69.66 rad/s

Explanation:

Suppose the handle of the crank is L = 1 m long. We can calculate the torque:

T = F*L = 258*1 = 258 Nm

Then the angular momentum is given to the handle within 0.27 seconds is

rad/s
