Are you asking for the name of those?
Final velocity = Vf=0 <span>
Initial velocity = Vi = 9.5m/s
Acceleration = a = -4.6m/s</span>²<span>
Time = t =? </span>
Now use the formula;<span>
Vf=Vi+at
<span>0=9.5 - 4.6m/s</span></span>²t
<span>
-9.5 = -4.6m/s</span>²(t)
9.5/4.6 = t<span>
<span>T= 2.01s</span></span>
The question involves the knowledge of kinematics and dynamics. The answers are;
a) Time taken to stop the car = 10 s
b) The operation that slows the car is Friction
c) The size of the force = 1200 N
<h3>
What is Deceleration ?</h3>
Deceleration is the opposite of acceleration. When an object is going to rest, it will be decelerating and the final velocity will be equal to zero.
Given that the driver of a car moving at 15 m/s along a straight level road applies the brakes. The car decelerates at a steady rate of 3/2 m/s²
a) How long does the car take to stop can be found by using the formula
v = u - at
Where
Substitute all the parameters into the formula
0 = 15 - 1.5t
1.5t = 15
t = 15/1.5
t = 10 s
b) The description of the operation that slows the car down after the brake pedal is pressed is simply friction.
c) If the mass of the car is 800. The size of the force slowing the car down will be F = ma
F = 800 × 1.5
F = 1200 N
Therefore, the time taken to stop the car is 10 s and the force slowing the car down is 1200 N

Answer: The plant will taller than its actual height.
To find the density of any object, you need to know the Mass (grams) of the object, and its Volume (measured in mL or cm³). Divide the mass by the volume in order to get an object's Density.
