Question

A train is moving at a velocity of 15 m/s is accelerated to 24 m/s over a 12 second period. What is the trains acceleration?

Answer 1

Step-by-step explanation:

velocity = 15 m/s

accelerated to = 24 m/s

time = 12 seconds

a = acceleration

u = final velocity

u0 = starting velocity

t = time

a = u - u0 = t

a = (24 m/s - 15m/s) / 12 s = (9 m/s) / 12 =0,75 (m*s^2)
