An electric train starting from rest is uniformly accelerated in a distance of 40m to a velocity of 10m/s, for this journey.

Question

(I).Calculate the time taken by the train.

(II). The acceleration of the train.

Answer 1

vf^2=vi^2+2ad solve for acceleration a, vi=0

knowing acceleration a
d=1/2 a*time^2
time=sqrt(2*distance/acceleration)
