A block is at rest on a horizontal frictional surface. A string is attached to the block, and is pulled with a force of 65.4 N at an angle theta above the horizontal. After the block is pulled through a distance of 1.35 m, its speed is 1.69 m/s, and 85.0 J of work has been done on it. Part A: Find the mass of the block. Part B: What is the work done by normal force in this case? Explain. Part C: Let’s say you are lifting this block in air instead of pulling it on the ground and then let go of it. How high will you have to lift this block to reach this same speed of 1.69 m/s moments before it touches the ground?

A box slides down a plank of length d that makes an angle of θ with the horizontal as shown. μk is the kinetic coefficient of friction and μs is the static coefficient of friction. Enter an expression for the minimum angle θ (in degrees) the box will begin to slide. Enter an expression for the nonconservative work done by kinetic friction as the block slides down the plank. Assume the box starts from rest and θ is large enough that it will move down the plank. For a plank of any length, at what angle θ (in degrees) will the final speed of the box at the bottom of the plank be 0.55 times the final speed of the box when there is no friction present? Assume μk = 0.35.

A block of weight w = 25.0 N sits on a frictionless inclined plane, which makes an angle θ = 30.0 ∘ with respect to the horizontal, as shown in the figure. A force of magnitude F = 12.5 N applied parallel to the incline, is just sufficient to pull the block up the plane at constant speed. Part A The block moves up an incline with constant speed. What is the total work Wtotal done on the block by all forces as the block moves a distance L = 2.70 m up the incline? Include only the work done after the block has started moving at constant speed, not the work needed to start the block moving from rest. Part B What is Wg, the work done on the block by the force of gravity w⃗ as the block moves a distance L = 2.70 m up the incline? Part C What is WF, the work done on the block by the applied force F⃗ as the block moves a distance L = 2.70 m up the incline? Part D What is WN, the work done on the block by the normal force as the block moves a distance L = 2.70 m up the inclined plane?
