Q1. A dockworker loading crates on the ship finds that a 24 kg crate, initially at rest on a horizontal surface, requires a 74N horizontal force to set it in motion. Though, after the crate is in motion, the horizontal force of 51N is required to keep it moving with a constant speed. Find the coefficients of static and kinetic friction between crate and floor.
Q2. A simple pendulum in a science museum entry hall is 3.51m long, has a 1.25kg bob at its lower end, and swings with an amplitude of 10.50 degrees. How much time does the pendulum take to swing from its extreme right side to its acute left side?
