Cheetahs can accelerate to a speed of 21.8 m/s in 2.55 s and can continue to accelerate to reach a top speed of 28.1 m/s . assume the acceleration is constant until the top speed is reached and is zero thereafter. let the +x direction point in the direction the cheetah runs. express the cheetah's top speed vtop in miles per hour (mi/h) .
starting from a crouched position, how much time totall does it take a cheetah to reach its top speed and what distance d does it travel in that time?
if a cheetah sees a rabbit 122.0 m away, how much time ttotal will it take to reach the rabbit, assuming the rabbit does not move and the cheetah starts from rest?
