At 15 minutes past the hour, a 47.0 g mouse runs up a grandfather clock and sits himself down at the end of the minute-hand. If the minute-hand for the clock is 16.0 cm long, what is the magnitude of the torque exerted by the mouse on the minute-hand? Give your answer in the standard units of N m.

Answer 1

mass = 0.047 kg
weight = 0.047 * 9.81 = 0.461 Newtons
lever arm = 0.16 meter
toque = 0.461 * 0.16 Nm
