A 5.2 kg bucket of water is raised from a well

by a rope. The acceleration of gravity is 9.81 m/s^2.If the upward acceleration of the bucket is 4.0 m/s^2, find the force exerted by the rope on the bucket of water.
Answer in units of N.

1 answer

F up
m g down

F = m a
Fup - m g = m a
so
Fup = m (g+a)

= 5.2 (9.81 + 4) Newtons
