A block of mass m is initially at rest at the highest point of an inclined plane, which has a height of 5.1 m and has an angle of θ = 16° with respect to the horizontal. After being released, it is found to be moving at v = 0.55 m/s a distance d after the end of the inclined plane as shown. The coefficient of kinetic friction between the block and the plane is μp = 0.1, and the coefficient of friction on the horizontal surface is μr = 0.2. Find the distance, d, in meters.

Let a body of mass m = 1 kg be dropped from a height by an inclined plane that forms an angle a = 15 ° with the horizontal, which has a length OA = 2 m and a coefficient of friction 4 = 0.15. Then it continues along a horizontal plane also of length d = 2 m and with friction coefficient pz = 0.1. At the end of this plane it collides with a pendulum of mass M = 2 kg and length L = 2 m. As a result of the collision the body of mass "m" stops and the pendulum starts moving. It is required: a) Body speed "m" when reaching the end of the inclined plane. b) Body speed "m" when reaching the end of the horizontal plane. c) Speed ​​of the pendulum of mass "M" just after the collision. d) Is the elastic shock? e) Maximum height "h" reached by the pendulum and the value of angle 0 formed by the pendulum cable with the vertical at that point. (See figure) Note Define precisely all the physical quantities used. In mathematical developments clearly justify the steps.% 3D m-1 kg d = 2 m L = 2 m0 A =…

A 1.5-kg box is released from rest on a frictionless surface that is sloped at θ = 35◦ above the horizontal.After sliding 1.0 m down the slope, the box transitions smoothly to a rough, horizontal surface, slides forsome distance, and then comes to a stop. If the coefficient of kinetic friction between the box and thehorizontal surface is 0.12, how far along the horizontal surface does the box travel?

A box with a mass of 7.24 kg is held at the top of frictionless inclined plane of length L = 10.9 m and an inclination angle 0 = 26.9 degrees above the horizontal. The box is released from rest and stops at a distanced = 22.62 m from the bottom of the inclined plane along the rough horizontal surface. What is the coefficient of kinetic friction between the box and the rough horizontal surface?
