Answer:
Acceleration of the train is \(10\ m/s^2\)
Explanation:
It is given that,
Initial speed of the train, u = 25 m/s
Final velocity of the train, v = 75 m/s
Time taken, t = 5 s
Charge in speed, \(v-u=75-25=50\ m/s\)
Acceleration of the train is given by change in speed per unit time. It is given by :
\(a=\dfrac{v-u}{t}\)
\(a=\dfrac{50\ m/s}{5\ s}\)
\(a=10\ m/s^2\)
So, the acceleration of the train is \(10\ m/s^2\). So, the correct option is (c).
