Question

A cheetah starts from, rest, and accelerates at 2 m/s² for 10 seconds. Calculate : 

(a) the final velocity 

(b) the distance travelled.

Answer 1

Initial velocity,

u=0m/s

Final velocity, v=?

Acceleration, a=2m/s²

Time, t=10s

(a)Using,

v = u + at

v=0 + 2 x 10= 20 m/s

(b)Distance travelled is:
