Question

20 kms bike speed 40 1hour

​

Answer 1

Answer:

I Think your question is

A bike covers 20 km at the initial speed of 40 km/ hr in 1 hour.

Find acceleration?

Step-by-step explanation:

As per given

u=20 km/hr.

t=1 hr.

s=20 km

So

$s = ut + \frac{1}{2} a {t}^{2}$

$20 = 20(1) + \frac{1}{2} a(1) {}^{2} \\ 20 = 20 + \frac{a}{2} \\ a = 0$
