Question

1. A cheetah starts from rest, and accelerates at 1.5 m/s² for 10 seconds.

Calculate:

a) the final velocity

b) the distance travelled​

Answer 1

Answer:

Explanation:

a) v= u+at

v= 0+(1.5)(10)

v= 15m/s from the start

b) s= (v+u)/2*t= 15*5 = 75m

Answer 2

Explanation:

Initial velocity, u = 0 m/s

Final velocity, v = ?

Acceleration, a = 2 m/s2

Time, t = 10s a) v = u + at = 20 m/s

b) s = ut + 1/2at2 =
