A chain of length (L) and mass (m) perpendicularly to a table top. If you let it fall off as shown, prove that the maximum force the chain exerts on the table top is 3mg​

The motor m applies a time-varying force of f (200 t) n, where t is in seconds. box b with mass 200 kg starts from rest, and the coefficients of kinetic and static friction are 0.2 and us 0.3 the acceleration due to gravity is g 9.8 m/s2 b 300 a) find the time ' when the box starts to move. b) calculate the speed of the crate at 3 s c) calculate the power delivered by the motor at t 3 s

How is the gravitational force related to the distance between two objects?
