a) A toy car of mass m = 6.11 kg goes going around a circular track of radius r = 2.74 m every 35.5 seconds. Find F, the magnitude of the inward force needed to keep it moving in a circle. N b) The same 6.11 kg toy car now starts at rest on the same track, and accelerates at a constant rate to final speed v = 1.65 m/s in time t = 8.9 seconds. At the instant it reaches its final speed, find:N N N
