A 3.6 kg bucket of water is raised from a well by a rope. If the upward acceleration of the bucket is 3.7 m/s2, find the force exerted by the rope on the bucket.N

A6.00 kg box sits at rest at the bottom of a ramp that is 8.00 m long and is inclined at 30.0° above the horizontal. The coefficient of kinetic friction is Hk = 0.40, and the coefficient of static friction is us = 0.43. Part A What constant force F, applied parallel to the surface of the ramp, is required to push the box to the top of the ramp in a time of 6.00 s?

m A person is pushing a wooden crate of mass mo = 20 kg at a constant speed vo = 1.2– for Ax = 3 m along a rough horizontal floor that has a coefficient of friction µk = .4.

A block and a ball are connected by a string as shown in the figure. The block sits on a level, rough surface. The coefficient of static friction between the block and the surface is μ = 0.841. The ball hangs freely from the string. The mass of the block is 18.82 kg. What is the largest mass of a ball you could hang from the string without causing the block to slide?

Two packing crates of masses m, = 10.0 kg and m2 = 3.00 kg are connected by a light string that passes over a frictionless pulley as in the figure below. The 3.00 kg crate lies on a smooth incline of angle 42.0°. Find the acceleration of the 3.00 kg crate. m/s2 (up the incline) Find the tenslon in the string. N

A man is trying to move an object (m 14.0 kg) by pulling upward on the rope at an angle of 53° above the horizontal. The coefficient of kinetic friction is 0.300 between the object and the ground.
