The train acquires a speed of 0.6 s / m 10 s after the start of movement. How long after the start of the movement the speed of the train will become equal to 3 m / s.
Given:
t1 = 10c
U1 = 0.6m / s
U2 = 3m / s
t2-?
Decision:
First, we find the acceleration, a = U1 / t1 = U2 / t2
Let us express t2
t2 = U2 / U1 * t1
t2 = 3 / 0.6 * 10 = 50 (c)
Answer: t2 = 50c
