Question

A bus increases its speed from 36 km/h to 72 km/h in 2s find acceleration of bus​

Answer 1

Explanation:

u = 36 km / h = 10 m / s

v = 72 km / h = 20 m / s

Now,

a = v - u / t

a = 20 - 10 / 2

a = 10 / 2

a = 5 m / s²

Hope it helps!!!!

Answer 2

Final velocity is = 72 km / h = 20 m/s

initial velocity is = 36 km/h = 2 m/s

time taken = 2 sec so the acceleration is = 20-10/2

= 5m/s²
