calculate acceleration of the player.  (b) How far does the player slide before coming to rest?

A 10.0 kg mass hangs from a rope, as shown in the figure. The rope passes over a fixed pulley, then under a movable pulley, and is attached to the ceiling as shown. The movable pulley has a mass m attached to it and moves at a constant speed. Find the tension in the rope. Assume that the masses of the pulleys are negligible.

A skier slides straight down an incline of 25 degrees without using her poles.  The slope itself is 96 meters long, and the skier starts from rest at the top. What would the velocity of the skier be at the bottom of the incline if friction can be neglected? What would your answer be to the previous question if the coefficient of kinetic friction between the skis and the snow is 0.13 on the incline? Upon reaching the bottom of the incline in part b, she reaches a flat portion, and decides to just let friction slow her to a stop. How far does the skier travel along the horizontal portion before coming to a stop, if the coefficient of kinetic friction is 0.28 on the flat portion?

A monkey pushes a box of mass 25 kg in a straight line across a rough floor. The applied force F has magnitude 85 N and acts downward at an angle 0 = 10° with respect to the horizontal, as shown below. The box is initially at rest at the position x/ a). Find the coefficient of friction between the box and the floor. and it has speed v2 = 0.55 m/s at position x2 = 3.50 m. 0 m, b). What is the net work done? c). How much work (magnitude and sign) is done by the friction force? m Hint: this q involves constant acceleration, Newton's laws, work

The system is released from rest in the position shown. Calculate the tension T in the cord and the acceleration a (positive if to the right, negative if to the left) of the 37-kg block. The small pulley attached to the block has negligible mass and friction. (Suggestion: First establish the kinematic relationship between the accelerations of the two bodies.) Answers: T = a = H₂= Hk = μ = 0.49 4 i 37 kg 38 kg N ! m/s²

Three stacked blocks have a downward force F' exerted on them as shown: Assume the system is at rest (such as blocks stacked on a stationary table). If m = 6.5 kg and F' = 9.9 N, what is the normal force exerted on the 5m block by the 8m block? Express your answer in N, to at least one digit after the decimal point.

Given this image, assume it has friction. After rolling down the left hill, the boulder then continues up an adjacent hill on the right, reaching a vertical height of 25m before coming to a stop. It travelled a total distance of d= 500m. Calculate the average friction force on the boulder.

At Ted's request, Bill pushes the pizza box across the granite countertop towards Ted. When the box leaves Bill's hand it is sliding at 2.60 m/s. The box comes to rest over a distance of 110 cm. What is the coefficient of kinetic friction, uk, between the pizza box and the countertop? (Ignore air drag.)
