Question

If a Ferrari , with an initial velocity of 10 m/s, accelerates to a speed of 26 m/s in 4 seconds. What was its average acceleration?

Answer 1

Accel = Vf - Vi t
Accel= 50 m/s/s Vf= x
Vi= 10 m/s
t= 3 s
(3 s)50 m/s/s= x – 10 m/s (3 s) 3s
150 m/s/s = x – 10 m/s + 10 m/s/s + 10 m/s

Answer x=160 m/s
