A mass m = 1.05 kg slides without friction from rest on a surface making a quarter circle with radius R = 1.55 m as shown in Figure 1. Then it lands on the top surface of a cart with mass M = 11.3 kg, that slides without friction on a horizontal surface. (In practise this cart could be a slider on an air track). Between the top of the cart and the mass m, the coefficient of static friction is μs = 1.07 and the coefficient of kinetic friction is μk = 0.959. The mass m slides a distance along the top of the cart but does not fall off. Figure 1: Diagrammatic representation of a block of mass m at the top of a quarter-circle surface of radius R that slopes down and to the right with decreasing absolute gradient towards a cart of mass M. The cart itself is resting on a horizontal surface. Part 1) What is the speed of the mass m immediately before it lands on the cart, M? v = ms−1 Part 2) What is the speed of the cart, M, when there is no longer any relative movement between m and M? V = m/s Part 3) How much mechanical energy is lost during the collision? (while m comes to rest relative to M). ΔE = −J Enter a positive number in the box if the final mechanical energy is less than the initial mechanical energy.

A block of mass m = 4.00 kg, starting from rest, slides down a frictionless inclined plane (ramp) of length 3.00 m. The plane is inclined by an angle of θ = 25.0∘ to the ground. At the bottom of the plane, the block slides along a rough horizontal surface with a coefficient of kinetic friction μk = 0.200 until it comes to rest. Let y = 0 represent a position along this horizontal surface. a) What is the initial mechanical energy (kinetic plus potential) of the object? b) What is the speed of the block when it reaches the bottom of the ramp? c) What is the work done by the friction force? d) What is the magnitude of the friction force on the horizontal surface? e) How far does the object slide along the horizontal surface before stopping?

A block of mass m = 100 kg is on an inclined plane as shown where ∅ = 20 degrees and θ = 40 degrees. The coefficient of static friction is μs = 0.35 and coefficient of kinetic friction is μk = 0.3 . Determine the friction force, F, acting on the block when force P with a magnitude of 200 N is applied to the block, which remains in equilibrium. Determine the magnitude of the force, P, required to initiate motion of the block up the slope from rest. Determine the magnitude of the friction force F acting on the block if P = 900 N.
