The brakes applied on a car produces an acceleration of 8 m/s² in the opposite direction to the motion. If the car takes 3 seconds to stop after the application of brakes, the distance it travels during the time will be? Anyone who will answer this question correct will be marked as brainliest.

Answer:
Hi there!
Here acceleration will be negative.
So,
a= -8 m/s2
t= 3 s
v= 0 m/s
s=?
According to the first equation of motion,
v = at + u
0= (-8)(3)+u
0= -24 +u
24=u
u =24 m/s
According to second equation of motion,
s = ut + (1/2) at2
s= (24)(3)+ (1/2) (-8)(9)
s=36 m
Hope this helps you.
