m = mass of the ball being raised
h = height to which the ball is raised = 0.5 m
v₀ = initial speed given to the ball = 3
v = final speed of the ball at its lowest position = ?
using conservation of energy
final kinetic energy at the lowest point = initial kinetic energy + initial potential energy
(0.5) m v² = (0.5) m v₀² + mgh
dividing each term by "m"
(0.5) v² = (0.5) v₀² + gh
inserting the values
(0.5) v² = (0.5) (3)² + (9.8) (0.5)
v = 4.34 m/s
Answer:
a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact.
Explanation:
i don't have one
The statement "<span>When an electron is added to a neutral atom of an element to form a negative ion, the resulting change in energy is referred to as the electron potential of that element." is false.

Gives you energy to burn off
Answer:
the force on an object is equal to its mass times its acceleration.
Explanation:
the more heavier the object (lawn mower) the more time it will take to cut the grass due to that the tv show will be gone
