Question

a bus started from rest and attains a velocity of 25 km/hr in 15 min.find the acceleration. please explain step bystep. sorry. i given this as maths. but physics

Answer 1

Hi,

Here is your answer

Given:

Initial Velocity(u)=0m/s

Final Velocity(v)=25km/hr=7m/s

Time(t)=15 min=900s

To Find:

Acceleration(a)

Solution:

Acceleration is given by the formula

a=(v-u)/t

Substituting the given datas in the equation.

We get,

a=(7-0)/900

a=7.78×10^-3m/s²

Notes:

1. Remember to convert all the given datas to the SI units before calculating.

2. Acceleration is defined as the rate of change of velocity.

Hope this helps you.
