A roller-coaster car has a mass of 504 kg when fully loaded with passengers. The path of the coaster from its initial point shown in the figure to point B involves only up-and-down motion (as seen by the riders), with no motion to the left or right. Assume the roller-coaster tracks at points ® and ® are parts of vertical circles of radius r, = 10.0 m and r2 = 15.0 m, respectively. (a) If the vehicle has a speed of 20.6 m/s at point ©, what is the force exerted by the track on the car at this point? N (b) What is the maximum speed the vehicle can have at ® and still remain on the track? m/s

On Mars, a ball is rolling from a ground to a hill, and we know the height of the hill, Z, is 10 m, and the initial velocity ofthe ball on the ground and the final velocity on the hill are known: V1 = 20 m/s and V2 = 10 m/s, respectively. The mass ofthe ball, m, is 4 kg. The gravitational acceleration on Mars, gMars, is 3.7 m/s2. Please calculate 1) the change in kineticenergy, ΔKE, in J and 2) the change in potential energy, ΔPE, in J, of the ball for the rolling process.
