Q2. A roller coaster, (h1 = 35 m, h2 = 12 m, h3 = 21 m), is pulled up to point A where it and its screaming occupants are released from rest. Assume no friction; compute the speed at points B, C and D.
Q3. A car takes 16 s to go from v = 0 to v = 50 m/s at approximately constant acceleration. If you wish to find the distance travelled using the equation d = 1/2 at2, what value should you use for a?
