Question

A train moving with velocity of 54 km initiated so that it will ocity becomes 72 km per hour in 15 seconds find the acceleration of the train

Answer 1

Hi.

Here is your answer---

___________________

Given---

Initial Velocity(u) = 54 km/hr.
Final Velocity(v) = 72 km/hr.
Time(t) = 15 seconds.

Using the Formula,

  Acceleration = (v - u)/t
                       = (72 - 54)/15
                       = 18/15
                       = 6/5
                       = 1.2 km/s².
                       = 1200 m/s².

Thus, Acceleration Produced by the Car is 1200 m/s².
