As shown in the figure below, three blocks with masses m₁ = 4.8 kg, m2 = 14 kg, and m3 = 18 kg, respectively, are attached by strings over frictionless pulleys. 1711 m2 ms The horizontal surface exerts a 32 N force of friction on m2. If the system is released from rest, use energy concepts to find the speed (in m/s) of m3 after it moves down 3.0 m. m/s
The speed of a block moving on a horizontal frictional surface changes from vi = 15 m/s to vf = 12.5 m/s in a distance of d = 9.5 m. How long in seconds did it take for the block to slow by this amount, assuming the acceleration is constant? If the block has a mass of 1 kg, What is the power supplied to the block by friction? What is the coefficient of kinetic friction between the block and surface μk?
A 2.0kg block starts with a speed of 10. m/s at the bottom of a plane inclined at 35° to the horizontal. The coefficient of sliding friction between the block and the plane is 0.30. use the work-energy theorem to determine how far the block slides along the plane before momentarily coming to rest. I know the answer is 6.2, I just don’t know how to get to it.

Calculate the work done (in J) by the force of friction as the sled moves 30.0 m up the hill. (Hint: Think about the direction of the friction force. Should it be different than the direction shown in the figure?). Calculate the work done (in J) by the tension force in the rope on the sled over this distance.
