The formula to calculate the net work performed on an object is:
\[ W = \frac{1}{2} m v_f^2 - \frac{1}{2} m v_i^2 \]
Where:
Net work is defined as the total change in work performed by the forces acting on an object.
Let's assume the following values:
Using the formula:
\[ W = \frac{1}{2} \times 10 \times 5^2 - \frac{1}{2} \times 10 \times 2^2 = 125 - 20 = 105 \text{ J} \]
The Net Work is 105 J.
Let's assume the following values:
Using the formula:
\[ W = \frac{1}{2} \times 15 \times 7^2 - \frac{1}{2} \times 15 \times 3^2 = 367.5 - 67.5 = 300 \text{ J} \]
The Net Work is 300 J.
