Question

a car starts from rest and moves along x- axis with constant acceleration for 5 m per second sq for 8 sec if it then continuous with constant velocity what distance will in 12 sec since it started from rest​

Answer 1

Answer:

Distance covered is 360m.

Explanation:

Given,

u=0( because the objects starts from rest)

a=5m/s²(given)

t=8 s(given)

Now, v=u+at

v=0+5(8)

v=40m/s

Now, t=12s,

by, s=ut+1/2at²

s=0(12)+1/2(5)(12)²

s=1/2(5)(144)

s=5×32

s=360m.

Hope it helps you!
