Question

The acceleration of gravity is 10 m/s 2 . What is the acceleration of a 62 kg pail of cement that is pulled upward (not sideways) with a force of 424 N? Answer in units of m/s 2 .

Answer 1

Force downwards = mg = 9.81 x 62 = 608.22 N

Force upwards = 424 N

Net force downwards = 608.22 - 424 = 184.22 N

Acceleration downwards = 184.22 / 62 = 2.97 m/s²
