Q1. A student tries to push a box that has a mass of 57.0 kg. The coefficient of static friction is 0.610 and the coefficient of kinetic friction is 0.380. If the student pushes the box with a horizontal force of 357N.

What is the actual force of friction?

Q2. The springs of a 1300 {rm kg} car compress 6.0 {rm mm} when its 62 {rm kg} driver gets into the driver's seat. If the car goes over a bump, what would be the frequency of vibrations?
