Complete Question
A ball having mass 2 kg is connected by a string of length 2 m to a pivot point and held in place in a vertical position. A constant wind force of magnitude 13.2 N blows from left to right. Pivot Pivot F F (a) (b) H m m L L If the mass is released from the vertical position, what maximum height above its initial position will it attain? Assume that the string does not break in the process. The acceleration of gravity is 9.8 m/s 2 . Answer in units of m.What will be the equilibrium height of the mass?

Explanation:
Image result for The energy from the sun can be used in many different ways. Describe two examples of how humans use the energy from the sun in their everyday lives. Make sure that one of your examples includes an energy transformation and explain the form it takes after it is transformed.
Solar energy is transformed into other energy forms for our use on Earth – energy for food (chemical energy), electrical energy and heat energy. Energy from the Sun is transformed into chemical energy, which is passed along in a food chain. Without the Sun, there would be no life on Earth

Answer:
<em>The displacement of the object is -8 m</em>
Explanation:
<u>Displacement</u>
The displacement of a moving object can be calculated as the area under (or above) the graph of velocity vs time.
If the area is below the y-axis, then the displacement is negative. Otherwise is positive.
It's important to differentiate displacement from distance. Displacement takes into consideration the direction of the movement. Distance does not and it's always positive.
From the graph provided, we can see the velocity from t=12 s from t=16 s is negative, and the displacement will also be negative.
The displacement is calculated as the area of the triangle with base b=16-12= 4 seconds and height = -4 m/s, thus:
The displacement of the object is -8 m
