Final answer:
To translate the quadratic function y=5x² 5 units up, the new function becomes y=5x²+5, shifting the graph upward without altering its shape.
Step-by-step explanation:
The original question pertains to a function transformation in the context of mathematics, specifically translating a quadratic function. However, the additional context provided relates to physics problems involving motion, trajectory, and work done by forces, suggesting a misinterpretation of the question's subject matter.
Corrected Response:
Given the function y=5x², to translate it 5 units up means to add 5 to the entire function, resulting in the new function y=5x²+5. This translation does not change the shape of the graph but shifts the entire parabola 5 units upward in the y-direction on the coordinate plane.
