2. A 3.80-kg hanging block is pulling against a 2.50-kg block on a tabletop, as shown, via a string over a pulley that is massless and frictionless. At the same time, a constant external force F = 5.50 N is pulling the tabletop block to the right, as shown. There is a static friction coefficient is = 0.75, and kinetic friction coefficient dx = 0.15, with the tabletop. (a) The blocks are initially stationary. With a calculation, determine whether the...

You are pulling a 6.8 kg box with rope with a force of 5.5 N. The rope is 35° above thehorizontal. For a while you are pulling across ice that is very smooth. Later you reach a patch of snow which has a kinetic coefficient of friction of 0.2 and a static coefficient of friction of 0.35 with the box. A)Draw the free body diagrams for the box when it is on the ice and when it is on the...

Block A of mass 10 kg sits on top of Block B of mass 15 kg. Block B is being tugged by a force F and Block A is being tugged by a force FA . FA makes an angle ? = 10degrees with the horizontal and is a 7N force. The coefficient of static friction between the two blocks is .01while the coefficient of kinetic friction between the floor and Block B is given as .5(see diagram below). Force...

A horizontal force of 4.50 N is applied to a 1.50-kg block, initial at rest on a table with a level surface. Will the block move if the coefficient of static friction is µs = 0.580? What is the coefficient of static friction if it just begins to move? What is the acceleration of the block if the coefficient of kinetic friction is 0.150?

Suppose a block of mass m is placed onto a horizontal surface and a horizontal pulling force P is applied to the block. Draw a free-body diagram for the block and apply Newton’s 2nd law to the block. >> Suppose that a horizontal applied force P begins pulling on the block with a steadily increasing force, starting from an applied force of zero. Once static friction is overcome, the applied force is quickly adjusted such that the block moves with...
