A loaded penguin sled weighing 60 N rests on a plane inclined at 20 to the horizontal. Between the sled and the plane the coefficient of static friction is 0.27, and the coefficient of kinetic friction is 0.13. (a) What is the minimum magnitude of the force F, parallel to the...

A 1.40- block is on a frictionless, 20 inclined plane. The block is attached to a spring ( = 40.0 ) that is fixed to a wall at the bottom of the incline. A light string attached to the block runs over a frictionless pulley to a 60.0- suspended mass. The suspended mass is given...
