Cheetahs fastest of the great cats can reach 45 in 2, Ask an Expert

Academics

Q1. Cheetahs, fastest of the great cats, can reach 45 in 2 starting from rest. Assume that they have constant acceleration throughout that time, find their acceleration (in (a) and (b) ) and the distance (in (c) and (d) ) Q2. They travel during that time.

Q2. A ball is thrown straight downward with an initial speed of 8.00 m/s, from a height of 30.0 m. After what time interval does it strike ground?
