Answer: The potential energy associated with a mass attached to a spring depends on how much the spring is stretched or compressed. ... The gravitational force on the mass is −mg (“−” because the force points down). The force is the negative of the slope on the potential energy versus position graph.

The initial velocity of the glider was
.
Answer:
The answer is they utilized light in a few spots to enlighten the subjects and to demonstrate their volume as masses.
Explanation:
That is the reason every one of the particles that move at the speed of light (e.g. photons) have zero rest mass. As a molecule with mass methodologies the speed of light, its vitality increments and winds up unbounded at the speed of light, which is the motivation behind why it can never be quickened to achieve that speed. However, you can state that the photon has relativistic mass on the off chance that you truly need to. In current wording, the mass of a protest is its invariant mass, which is zero for a photon.
Answer:
Energy loss ΔE = 8.08 (Approx)
Explanation:
Given:
Channel width = 8 m/s²
Before jump a1 = 0.50 m
After jump a2 = 4.75 m
Find:
Energy loss ΔE
Computation:
Energy loss ΔE = (a2 - a1)³ / 4a1a2
Energy loss ΔE = (4.75 - 0.50)³ / 4(4.75)(0.50)
Energy loss ΔE = 76.7656 / 9.5
Energy loss ΔE = 8.08 (Approx)
