C. The work done by the 5500.0 N force on the elevator is 275,000 J.
<h3>
Work done by the applied force</h3>
The work done by the 5500.0 N force on the elevator is calculated as follows;
W = Fd
where;
- F is the applied force
- d is the displacement
W = 5500 x 50
W = 275,000 J
Thus, the work done by the 5500.0 N force on the elevator is 275,000 J.

Answer:
Horizontal Component = 129.9 km/h
Vertical Component = 75 km/h
Explanation:
When a vector is resolved on the x-axis and the y-axis, the components so formed are called its rectangular components. The component along y-axis is called the vertical component and the component along x-axis is called horizontal component. These components can be given by following formulae:
Horizontal Component = v Cos θ
Vertical Component = v Sin θ
where,
v = velocity = 150 km/h
θ = angle = 30°
Therefore,
Horizontal Component = (150 km/h)(Cos 30°)
<u>Horizontal Component = 129.9 km/h</u>
Vertical Component = (150 km/h)(Sin 30°)
<u>Vertical Component = 75 km/h</u>
Answer:
a) 500 J
Explanation:
Potential energy can be defined as an energy possessed by an object or body due to its position.
Mathematically, potential energy is given by the formula;
Where,
P.E represents potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per seconds square.
h represents the height measured in meters.
In Science, the potential energy possessed by an object or body is the same as the work done by the object or body.
Since we know that the object possessed 500 Joules of potential energy; it would ultimately require to do a work of 500 Joules to lift the object.
Mathematically, work done = force * distance
But force = mass * acceleration due to gravity
F = mg; d = h
Substituting into the work done formula, we have;
Hence, Workdone = Fd = mgh
