A 4.0-kg block is on an incline plane of 30 degrees angle with respect to horizontal. a)What is the minimum coefficient of static friction (μs)min is need to prevent it from sliding down? b) If the surface μs is 0.30, less than (μs)min now, how much force(F) is needed to apply to the block horizontally to prevent it from sliding down?c) If F is doubled, what’s the acceleration of the block up the incline? Assume the coefficient of kinetic friction is 0.25.

A 1.50-kg block is on a frictionless, 30 degrees inclined plane.
The block is attached to a spring (k = 40.0N/m ) 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-g
suspended mass. The suspended mass is given an initial downward
speed of 1.40m/s. How far does it drop before coming to rest?
(Assume the spring is unlimited in how far it...
