Question

A train starting from a railway station and moving with uniform acceleration attains a speed of 40km/hr in 10 minutes. find its acceleration

Answer 1

initial velocity = 0
final velocity = 40 km/ hr
time = 10 min = 1/6 hr
acceleration = change in velocity / time

=>a=( 40-0)/(1/6)
= 40×6= 240 km/hr....
