Question

a train starting from a railway station attains a speed of 40 km/hr in 10 min. Find its acceleration.​

Answer 1

Explanation:

u = 0 km/hr

v=40 km/hr

=40 * 1000/60 m/s

=4000/6 m/s

t=10 min

=600 sec

v=u+at

4000/6=a(600)

40/36 m/s2 =a

Answer 2

Explanation:

given÷

u=0

v=40 km/hr =40×5/18

=100/9 m/s

time=10×60=600 second

acceleration= (100/9-0)/600

=1/54 ms^-2
