A cheetah lays on a rock in the Sahara when an antelope gallops by at a constant velocity of 24m/s (E). The cheetah, who was initially at rest but wants to play, begins to run after the antelope at a uniform acceleration of 0.36 m/s^2 (E). (a) At what time (other than t=0) does the cheetah catch up with the antelope?
(b) What is the speed of the cheetah when it catches u to the antelope?
(c) How far did the cheetah travel before catching up with the antelope?
