Question

a train starts from rest and moves with a constant acceleration of 2.0 metre per second square for half a minute.the brakes are there in the train comes to rest in 1 min.find the total distance moved by the train​

Answer 1

Answer:900m

Explanation:

u(initial Velocity)=0m/s

Acceleration to m / s²

Time=30sec

V(final velocity)=0m/s

Using the third equation of motion ,

s=ut+1/2at²

s =0*30+1/2*2*30²

s=900m
