Question

A train starts from rest and accelerate uniformly at the rate of 15m/s2 for 5 sec.calculate the velocity of train in 5sec
​

Answer 1

Acceleration of train = 5m/s^2

Time = 5 seconds

Initial velocity, u = 0 (as the train started from rest)

Now, By using the identity v = u + at, we will find the value of v

v = u + at

v = 0 + 5×5

v = 25

so the Final velocity of train, v = 25

Hence, The velocity of train in 5 seconds is 25 m

Hope It helps u:)

Answer 2

Answer:

75 m / sec

Explanation:

Given :

Initial velocity u = 0 m / sec

Acceleration a = 15 m / sec²

Time t = 5 sec

We are asked to find final velocity v :

Using first equation of motion :

= > v = u + a t

Putting values here we get :

= > v = 0 + 15 × 5 m / sec

= > v = 75 m / sec

Therefore , the velocity of train is 75 m / sec.
