Question

A train starting from a railway station and moving with uniform acceleration attains a speed of 40km h-¹ in 10 minutrs .find its acceleration.

Answer 1

Hey !!!

here , initial speed of trail u = 0 [ start from rest ]

final speed of train , v = 40km h -¹

= 40×40m / 60× 60s

= 11 .11 m s-¹

and time taken , t = 10 minutes

= 10 × 60 = 600s

Acceleration a *= v - u / t

a = 11. 11 - 0 / t

a = 11.11- 0/ 600

a = 11. 11 / 600m s-²

a = 0.0185 ms-² [ or ,1. 85× 10-²m s-²]

Hope it helps !!!
