Question

A racing car starts from rest and moves with an constant acceleration If it crosses the end point of 1st lap after 160min, which a velocity of 180kmph then find the length of lap

​

Answer 1

Answer:

u=0

v=180km/h= 180×5/18 = 50m/s

t=160min= 160×60=9600sec

a=v-u/t= 50/9600= 0.0052833333m/s²

s=at²/2= 0.00520833333×92160000/2

=4799999996928/2= 230000.9998464m
