<h2>Answer: 10.52m</h2><h2 />
First, we have to establish the <u>reference system</u>. Let's assume that the building is on the negative y-axis and that the brick was thrown at the origin (see figure attached).
According to this, the initial velocity 
has two components, because the brick was thrown at an angle 
:
(1)
(2)
(3)
(4)
As this is a projectile motion, we have two principal equations related:
<h2>
In the x-axis:
</h2>
(5)
Where:
is the distance where the brick landed
is the time in seconds
If we already know 
and 
, we have to find the time (we will need it for the following equation):
(6)
(7)
<h2>
In the y-axis:
</h2>
(8)
Where:
is the height of the building (<u>in this case it has a negative sign because of the reference system we chose)</u>
is the acceleration due gravity
Substituting the known values, including the time we found on equation (7) in equation (8), we will find the height of the building:
(9)
(10)
Multiplying by -1 each side of the equation:
>>>>This is the height of the building
Kinetic Energy I’m not 100% shure tho
Answer:
The speed of the vehicle was 21 m/s
Explanation:
Momentum can be defined as mass in motion
Momentum depends on the variables mass and velocity
The momentum of an object is equal to the mass of the object times the
velocity of the object
The given is:
→ A Jeep Rubicon has a mass of 2,630 kg
→ With a momentum of 55,200 kg m/s
We need to find the speed of the vehicle
→ The momentum = mass × speed
Substitute the values above in the rule
→ 55,200 = 2,630 × speed
Divide both sides by 2,630
→ speed = 20.99 ≅ 21 m/s
<em>The speed of the vehicle was 21 m/s</em>
