A 4,500-kg roller coaster cart has a speed of 4.76 m/sm/s when it reaches its first peak at a 99.0 mm height from the ground level. After descending, it climbs up the second hill which is 84.2 mm above the ground level. How fast is the roller coaster cart at the top of the second hill? Assume there is no friction with the rails and no air resistance during the cart's motion.

Problem 1 A roller coaster cart has a mass of 200.0kg, which includes its passengers. The cart is pushed off its beginning position by a spring with a spring constant of k 150.ON/m that has been compressed by Ax 0.50m from its equilibrium length. Friction is negligible everywhere, except for a 2-meter-long rough patch on the initial slide (see the figure below), where the coefficient of kinetic friction is uk 0.4. (For the purposes of calculation involving friction, here you...
