Which of the following body has a speed of 10 metre per second?

1. 36km/hr.
2. 54 km /hr.


Complete solution needed.​

Answer 1

initial velocity (u) = 36 km/hr or 10 m/s

final velocity (v) = 54 km/hr or 15 m/s

time taken (t) = 10 seconds

to find : acceleration

solution :

by using 1st equation of motion

v = u+at

15 = 10+10a

10a = 5

a = 1/2 or 0.5 m/s^2

hope it helps :)
