Answer:

8.975 m/
s^(2)

Step-by-step explanation:

Travel starting velocity (u) = 34.8 m/s

Achieved (final) velocity = 214.3 m/s

Travelling time(t) = 20 s

we know that, v =u +at

; where v= final velocity

u=start velocity

a=acceleration

t=time

Therefore,

His acceleration, a = (v-u)/t

=(214.3-34.8)/20

= 8.975 m/
s^(2)
