Question

A car travelling at20km/hour speed up to60km/hour in6second what is accelleration

Answer 1

Que. A car travelling at 20km/hour speed up to 60 km/hour in 6 second what is acceleration.

$\boxed{\boxed{\huge{\bf{Answer}}}}$

As per the information given in question both velocities are given in km/h but the time has been given in second. So we have to convert velocities into m/s.

To convert in m/s system we have to multiply in the constant $\frac{10}{36}$

After multiplying and solving these velocities we will get the following:

initial velocity = u = 100/18 m/s

final velocity = v = 100/6 m/s

as we know acceleration is the ratio of difference between the final velocity and initial velocity to the total time.

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