35 points to answer this question in easy and clear method........A racing car has a uniform acceleration of 5m/s^2.what distance will it cover in 20 seconds after starting from rest?

Answer 1

A=5m/s2 t=20 u=0(at rest)

A=v-u/t

5=v-0/20

100=v

D=ut+1/2at^2

=0(20)+1/2(5)(20)^2

=1/2×5×400

=1000m
