Question

A car accelerates on a highway from rest to 10m/s in 30 seconds. What is the magnitude of its average acceleration in m/s²?​

Answer 1

To Find:-

• Find the acceleration.

Given:-

• A car starts from rest and reaches to 10m/s within 30 seconds.

Solution:-

Here,

u = initial velocity

v = final velocity

a = acceleration

s = distance

t = time

As we know that :-

$\tt \: a = \dfrac{v - u}{t}$

$\tt \: a = \dfrac{ 10 - 0 }{30}$

$\tt \: a = \dfrac{ 1 }{ 3 }$

$\tt \: a = 0.33 \: {m/s}^{2}$
