Q. A crate of mass 150.0 kg lies at rest on a horizontal storage room floor. The coefficient of static friction between crate and floor is 0.72, and the coefficient of kinetic friction is 0.85. (You may suppose g = 10.0m/s2).
a) Suppose someone pulls on the horizontal rope attached to the crate. They slowly increase the tension in the rope. Illustrate a free body diagram of system.
b) Suppose someone pulls on a horizontal rope attached to crate with a force of 200N. Does the crate remain at rest or start moving? If it moves does it have constant speed or continue to accelerate? If it accelerates, what is its acceleration?
Under these conditions what is the frictional force on the crate?
c) Reply part (b) again if the pull on the rope is 1000N.
d) What force on the rope is required to start the crate sliding?
How much work did the movers do (horizontally) pushing a 190-{rm kg} crate 11.2 m across a rough floor without acceleration, if effective coefficient of friction was 0.60.
Suppose that the light is incident at right angles to the film. what is the minimum distance from the slits to the screen when 580 nm light is used.

A 0.50-kg object is attached to an ideal massless spring of spring constant 20 N/m along a horizontal, frictionless surface. The object oscillates in simple harmonic motion and has a speed of 1.7 m/s at the equilibrium position.
Find the distance point P on the tip of the blade has traveled in 3 sec. Also, find the magnitude of the acceleration of point P when t = 3 sec.
Car A uses tires for which the coefficient of static friction is 1.1 on a particular unbanked curve. The maximum speed at which the car can negotiate this curve is 25 m/s. Car B uses tires for which the coefficient of static friction is 0.65 on the s..
