The 3 equation for uniform acc
Question

A car starts from rest and accelerates uniformly to a speed of 180 kmh-1 in 10s. The distance covered
by the car in the time interval is 

Moderate
Solution

Given, u = 0, v = 180 kmh-1=50 ms-1

Time taken, t = 10s, a = v - ut = 5010 = 5 ms-2 

Distance covered by the car, 

                         s=ut+12at2=0+12×5×(10)2

                            =5002=250 m
