Question

Compute the acceleration of a car that starts from rest and reaches a velocity of 60 kilometers per hour in 10 seconds

Answer 1

The acceleration is 1.67 m/s²

Explanation:

Given:

Speed, s = 60km/hr

           s = $60 X \frac{1000}{3600}$ m/s

           s = 16.67 m/s

Time, t = 10 seconds

Acceleration, a = ?

We know:

$Acceleration = \frac{speed}{time}$

On substituting the value, we get:

$a = \frac{16.67}{10} \\\\a = 1.67 m/s^2$

Therefore, the acceleration is 1.67 m/s²
