Question

A bus moves with the speed of 50km/hr. If it accelerates at the rate of 1m/s^2 for 30 sec, then what will be it's final velocity?

Answer 1

Answer:

395/9 m/s

Explanation:

u=50 km/hr

=50*5/18

=250/18 m/s

v= ?

a=1 m/s²

t=30 s

Now, we know that a=(v-u)/t

So, v= at+u

      v=1*30+250/18

      v=30+250/18

     v=395/9 m/s
