Question

A car is moving with uniform acceleration of 5 M per second square find its velocity after 20 seconds if it started from rest also find distance covered

Answer 1

from 1 equation of motion
v=u+at
v=0+5x20
v=100m/s
displacement --from 3rd equation of motion
s=ut +1/2 at^2
s=0+0.5x5x20x20
s=1000m

Answer 2

acceleration=5m/s2

uniform velocity=0m/s

timetaken=20s

finalvelocity=u + at

                   =0 + 5*20

                    =100m/s

distance=u + v / 2 *t

              =0+100/2* 20

              =50*20

              =1000m
