Answer:
the Answer Would be D
Explanation:
From what I know light travels 300,000 km/second , travels at fast speeds and travels in a straight line
Answer:
2856.96 J
0
0

6.78822 m/s
Explanation:
= Initial velocity = 9.6 m/s
g = Acceleration due to gravity = 9.81 m/s²
h = Height
The athlete only interacts with the gravitational potential energy. Air resistance is neglected.
At height y = 0
Kinetic energy

At height y = 0 the potential energy is 0 as

At maximum height her velocity becomes 0 so the kinetic energy becomes zero.
As the the potential and kinetic energy are conserved
The general equation

Half of maximum height



The velocity of the athlete at half the maximum height is 6.78822 m/s
Answer:
D.
Explanation:
A solar system is a collection of planets, their moons, and other objects in orbit around a central star.
Ok but y I thought it was upside down tho...
