An antelope and a cheetah decide to race to a watering hole 1
km
away. The cheetah's top speed is 3x the top speed of the antelope,
so the cheetah is condent
she's got the win in the bag. From the starting line, the animals
accelerate uniformly to
their top speeds in 10 seconds. After 30 more seconds, the
exhausted cheetah stops for a
rest. The antelope is nowhere in the cheetah's sight, so the
cheetah decides to take a quick
2-minute nap. Upon waking, the cheetah again accelerates uniformly
to her top speed in 10
seconds and crosses the finish line at that speed. If the antelope
crosses the finish line in 3
minutes and 10 seconds, who wins the race? Draw a velocity vs time
graph for the cheetah's
motion.
graph is 100% correct if
condition of retardation of CHITAH is not considered
And in this question condition of retardation is not given
