When a car travelling at an initial velocity of 10 m/s applies the brakes and bring ... accelerates from rest for a time of 8 seconds with an acceleration of 3.2m/s^2?
Answer:
<h3>The answer is 3 kg</h3>
Explanation:
The mass of the object can be found by using the formula

f is the force
a is the acceleration
From the question we have

We have the final answer as
<h3>3 kg</h3>

It becomes a positive Iron
I think is a high-pressure system because it is only in one particular area.
Answer:

Explanation:
Given:
- area of piston on the smaller side of hydraulic lift,

- area of piston on the larger side of hydraulic lift,

- Weight of the engine on the larger side,

Now, using Pascal's law which state that the pressure change in at any point in a confined continuum of an incompressible fluid is transmitted throughout the fluid at its each point.



is the required effort force.
