A bus increases its velocity from 20m/s to 30m/s in 4s. Find its
acceleration.
(Ans: 2.5m/s?

Explanation:

:

Initial velocity ( u ) = 20 m / s

Final velocity ( v ) = 30 m / s

Time taken ( t ) = 4 second

:

Acceleration of a bus ( A ) = ?

We know,

The acceleration of bus = 2.5 m / s ²

Hope I helped!

Best regards!

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
