Question
A train is travelling with the velocity of 15m/s . It then accelerates at 0.5m/s^2 for 6 seconds . Calculate the velocity after the 6 seconds
Answers

a = .5 m/s^2
then
v = .5t + c m/s^2
when t = 0, v = 15
so 15 = .5(0) + c
c = 15
velocity = .5t + 15, when t = 6
velocity = .5(6) + 15 = ....
then
v = .5t + c m/s^2
when t = 0, v = 15
so 15 = .5(0) + c
c = 15
velocity = .5t + 15, when t = 6
velocity = .5(6) + 15 = ....
