A train accelarates uniformly in a straight line at 0.3m/s^2 from rest. Calculate the velocity 15 seconds after its departure. Calculate time taken to reach 30km/h and calculate Distance covered by the train
v₁=30km/h=30000/3600 =833.3 m/s
t₁=v₁/a=833.3/0.3 =2777.8 s.
s=v₁²/2a= 833.3²/2•0.3=1157314 m =1157 km
