Answer:

Problem:

A train accelerates to a speed of 20m /s over a distance of 150 m. Determine the acceleration (assume uniform) of the train

Given Data:

Vi (initial velocity) = 0 m/s

Vf (final velocity) = 20 m/s

d (distance)  = 150 m

a (acceleration) = unknown

Solution:

We can use the this formula in solving the problem above Vf² = 2ad since Vi = 0 m/s and to solve for acceleration, we can use a = Vf²/2d

a = Vf²/2d

 = (20 m/s)² / 2 × 150 m

 = 400 m²/s²  /  300 m

 = 1.33 m/s²

Answer:

the acceleration of the train assuming uniform acceleration is 1.33 m/s²
