Answer:
D. An image that is smaller than the object and is behind the mirror
Answer:
part(a) 151 m
part(b) 1.073 m/s2
part(c) 16.7 secs
Explanation:Firstly the person applied brakes 0.5 secs after seeing the red light hence the distance traveled during this time is
d=v*t
d=18*0.5
d=9m
For part (a)
I have corrected this question and now
The person was 160m from the intersection before applying the brakes as he traveled 9m before the brakes
He is now 151 m from intersection as
s=160-9
s= 151 m
part (b)
As it is given that velocity of the car is 0 at the intersection so we use this information in kinematic equation

here u=18m/s and s=151

To calculate time we can use the acceleration equation

Answer:
The acceleration is g.
Taking the upward direction as positive
V = Vy y - 1/2 g t^2
Taking the downward direction as positive
V = -V y + 1/2 g t^2
One can choose either direction as positive, but the acceleration is
the same as g (it is g) while the projectile is in the air.
