Question

A car is start to move from its rest and acquires velocity of 72km/hr. find its acceleration ​

Answer 1

Answer:

2$m/s^{2}$

Step-by-step explanation:

The Question is incomplete !

CORRECT QUESTION :  A car acquires a velocity of 72 km/hr in 10 s starting from rest. Calculate the acceleration.

Given:

Initial Velocity, u = 0

Final Velocity, v =  72km/hr = 72 × $\frac{1000}{3600}$ = 20m/s

Time,t = 10 sec

To Find:

Acceleration , a = ?

Formula:

$a= \frac{v-u}{t}$

Solution :

ON SUBSTITUTING THE VALUES

a = $\frac{20 - 0}{10}$ = $\frac{20}{10}$ = 2$m/s^{2}$
