A train accelerates to a speed of 20 m/s over a distance of 150 m. Determine theacceleration (assume uniform) of the train.
Question
Solution 1
To solve this problem, we can use the following kinematic equation:
v^2 = u^2 + 2as
where: v = final velocity = 20 m/s u = initial velocity = 0 (since the train starts from rest) a = acceleration (which we are trying to find) s = distance = 150 m
Rearranging the equation to solve for a gives:
