A car is moving at 72 km/her after covering a
distance of 100m his velocity is 54 km/hr calculate
the acceleration of the car?
​

Answer 1

hlo ❣

I am glad to help you..

$\huge {\underline {\underline {\mathbb {\blue{Answer:-}}}}}$

Given :-

u = 72 km/hr = 20 m/s

v = 54 km/hr = 15 m/s

s = 100 m

To find :-

acceleration

solution:-

$\huge{\pink{\boxed{\mathtt {v^2=u^2+2as}}}}$

=>15^2 = 20^2+2(a)(100)

=>225 = 400+200a

=> (225 - 400)/200}=a

=>a = 0.875 m/s^2
