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 1000-kg car rounds a curve on a flat road of radius 50 m at a speed of 15 m/s (54 mi/h). Will the car follow the curve, or will it skid? Assume: (a) the pavement is dry and the coefficient of static friction is μs = 0.60; (b) the pavement is icy and (a) μs = 0.25
