Question

A car accelerates uniformly on a straight road from rest to a speed of 180 km/ hr in 25sec . Find distance covered by the car in this time -interval

Answer 1

Explanation:

distance = 180 km per hour upon 25 second

180km/h=180×5 upon18

50m/s

d= s upon time

50 upon 25

d = 2 m /s

Answer 2

Answer

u=0

v=180km/h=75m/s

t=25s

a=?

s=?

a=v-u/t

a=75-0/25

a=3m/s^2

s=ut+1/2at^2

s=0*25+1/2*3*25*25

s=937.5m
