Question

A car goes from rest to 50 m/s in 20 s, what is its AVERAGE ACCELERATION.

b) What is that ACCELERATION as a fraction of g (acceleration of gravity)?

Answer 1

Answer #1

Given,

The initial velocity, v_i = 0 m/s (rest)

The final velocity, v_f = 50 m/s

The time, t = 20 sec

The acceleration, a = v / t

a = (v_f - v_i) / t

= (50 - 0) / 20

= 2.5 m/s²
