Question

A car moves with a speed of 36m / s, then because the road is deserted the speed increases, so that there is an acceleration of 1m / s2. When the addition comes 4s. Determine the final speed and the amount of distance traveled!

Answer 1

Explanation:

v=u+at

u=36m/s

a=1m/s^2

t=4s

v=36+4×1

v=40m/s

s=ut+1/2at^2

s=36×4+1/2×1×4^2

s=144+8

s=152m
