Answer:
c. joules
Explanation:
The rate at which a force displaces a mass a horizontal distance is measured in joules. In science, this phenomenon is known as work done.
Work done can be defined as the rate at which a force acting on an object or a body causes it to experience a displacement. The work done is a scalar quantity and is measured in joules (J).
Mathematically, work done is given by the formula;
Work done = force * distance
Where,
- F represents the force acting on a body.
- d represents the distance covered by the body.

Hi there!
We can begin by calculating the time taken to reach its highest point (when the vertical velocity = 0).
Remember to break the velocity into its vertical and horizontal components.
Thus:
0 = vi - at
0 = 16sin(33°) - 9.8(t)
9.8t = 16sin(33°)
t = .889 sec
Find the max height by plugging this time into the equation:
Δd = vit + 1/2at²
Δd = (16sin(33°))(.889) + 1/2(-9.8)(.889)²
Solve:
Δd = 7.747 - 3.873 = 3.8744 m
The equation of the graph is
Force = (mass) x (acceleration) .
The graph is a straight line that passes through the origin,
and its slope is the mass of the object being studied.
The answer is d. Wavelength
