Answer:
Refer to the attachment for solution (1).
<h3><u>Calculating time taken by it to stop (t) :</u></h3>By using the second equation of motion,
→ v = u + at
- v denotes final velocity
- u denotes initial velocity
- t denotes time
- a denotes acceleration
→ 0 = 5 + (-5/6)t
→ 0 = 5 - (5/6)t
→ 0 + (5/6)t = 5
→ (5/6)t = 5
→ t = 5 ÷ (5/6)
→ t = 5 × (6/5)
→ t = 6 seconds
→ Time taken to stop = 6 seconds

Fm= 91.88 N
Explanation:
Pascal principle
The pressure acting on one side is transmitted to all the molecules of the liquid because the liquid is incompressible.
The pressure is definited like this:
P=F/A
Where:
P: Pressure in pascals (Pa)
F: Force acting in the area (N)
A : Area where the force acts (m²)
Pascal principle
Pm=Ps
Fm/ Am= Fs/ As Formula (1)
Where :
Pm : Pressure on the master piston
Ps : Pressure on the slave piston
Fm : Force on the master piston (N)
Fs: Force on the slave piston ((N)
Am: master piston area (m²)
As: slave piston area (m²)
Area Formula (A)
A= π*R²
R : piston radius
Calculation of the weight of the car (W)
W= m*g= 2400 kg*9.8m/s²= 23520 N
W = Fs
Data
Fs = 23520 N
Dm = 1.5 cm
Ds = 24 cm
Rm = 0.75 cm
Rs = 12 cm
Am = π*Rm² = π*(0.75)²
As = π*Rs² = π*(12)²
Force exerted on the master cylinder
We replace data in the formula (1)
Fm= 91.88 N
The Otto Cycle can be used to describe how an internal combustion engine works, which allows your car to run by just filling it up with gas. <span>Each of the numbers shown in the figure (1 through 6) represent one stage of the Otto cycle, or one step of the internal combustion process. The common automobile engine is called a “4 Stroke Engine” because it has 4 strokes, which are the Intake Stroke, Exhaust Stroke, Compression Stroke, and Power Stroke. The “Combustion Process” shown in the Otto Cycle in the figure occurs between Strokes 3 and 4, and the “Heat Rejection” shown in the figurea occurs between Strokes 3 and 4.</span>
