Question 1 A roller coaster car of total mass m 645 kg starts at a level portion of the track, a height h1 = 24 m above the ground. It's initial speed is vo = 2.2 m/s. The car then descends down the track, around a loop-the-loop, up a small hill and then down to ground-level. After which, the car hits a spring, bringing it gently to rest. The track is sketched below. Assume no friction and no air resistance in this problem. a) What is the speed of the car at the smaller hill, a height hạ = 16 m above the ground? b) If the spring compresses a distance d = 2.3 m before bringing the car to rest, what must the spring constant be?
