If a car accelerates uniformly from rest and attains a speed of 40km/h in 10 second, how much distance it covers?

initial velocity (u) = 0 m/s

final velocity (v)= 40m/s

time = 10 seconds

now,

acceleration= (v-u)/t

= 40-0/10

= 4 m/s

now using the third equation of motion,

v^2-u^2=2as

(40)^2-0= 2×4×s

s= 40×40/2×4

= 200 m

hope it helps you
