Question

speed of train is increasing linearly with time the train passes
the hut with the speed 2m per sec and acquires a speed of 12 m per
sec after 10 sec what is the speed of the train in m/s ,5 sec after
passing the hut

Neha Gupta · Accepted Answer

Initial speed of the train is 2 m/s
after 10 s , its speed is 12 m/s
v = u + at
12 = 2 + 10a
a = 1 m/s2

Velocity after 5 s is:
v = 2 + 1(5)
v = 7 m/s

speed of train is increasing linearly with time .the train passes the hut with the speed 2m per sec and acquires a speed of 12 m per sec after 10 sec . what is the speed of the train in m/s ,5 sec after passing the hut.
