Question

Initial velocity 10 km and final velocity 20 km in 1 hr

Answer 1

★ Given :

Initial velocity (u) = 10 km/h

Final velocity (v) = 20 km/h

Time taken = 1 hr

$\rule{200}{1}$

★ To Find :

We have to find the acceleration.

$\rule{200}{1}$

★ Solution :

We know that,

$\Large{\star{\boxed{\tt{a = \frac{v - u}{t} }}}}$

______________[Put Values]

$\rm{\implies a = \frac{20 - 10}{1}} \\ \\ \rm{\implies a = \frac{10}{1}} \\ \\ \rm{\implies a = 10} \\ \\ \Large{\star{\boxed{\tt{a = 10 \: kmh^{-2} }}}}$
