Problema Solution

A train accelerates from 30 km/hr to 45 km/ hr in 5.0 seconds . Find it's acceleration and the distance it travels during this time.

Answer provided by our tutors

30 kmh = 8.33 m/s

45 kmh = 12.5 m/s

It's acceleration = (12.5-8.33)/5 =0.83 m/s^2

The distance S

S = (8.33+12.5)*5/2 = 52.075 m
