Question

a train starts with 90 kilometre per hour and attends 120 metre per second in 5 minute find the acceleration of train

Answer 1

Explanation:

u=25m/s(after conversion into m/s)

v=120m/s

t=5 s

a=120-25--:--5=95-:-5=19m/s^2

Answer 2

Hello buddy!!
Here is your answer...

u = 90 km/h = 25 ms^-1

v = 120ms^-1

t = 5 × 60 = 300 sec

a = v - u/t

= 120 - 25/300

= 95/300

= 0.316ms^-2

Hope, it helps you...
