Question

the speed of the bus increases from 25 km/hr to 70 km/hr in 5 seconds. Find the mean acceleration of the bus

Answer 1

Let a be the acceleration
a = ( v - u) /t
a = 70 - 25 / 5
a = 45/5
a = 9 m/s sq

Answer 2

Follow me and mark as BRAINLIEST

(a = acceleration)

a = $\dfrac{change\ in\ velocity}{time\ taken}$

a = $\dfrac{70-25}{5}$

a = $\dfrac{45}{5}$

a = $9m/s^{2}$
