Because the strength of the gravitational forces between two objects
depends on the distance between the objects' centers, and when your
elevation changes, so does the distance between your center and the
center of the Earth.
Answer:
Explanation:
Initial velocity (u) = 2 m/s
Displacement (s) = 2.5 m
Acceleration due to gravity(a)=9.81m/s^2
Final velocity (v) = ?
Now, formula is given by
v² = u² + 2×a×s
v² = 2² + 2×9.81×2.5
v² = 4 + 49.05
v² = 53.05
v = √53.05
v = 7.3 m/s
Answer:
An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision. Both momentum and kinetic energy are conserved quantities inelastic collisions.
Explanation:
Suppose two similar trolleys are traveling toward each other with equal speed. They collide, bouncing off each other with no loss in speed. This collision is perfectly elastic because no energy has been lost. In reality, examples of perfectly elastic collisions are not part of our everyday experience. Some collisions between atoms in gases are examples of perfectly elastic collisions. However, there are some examples of collisions in mechanics where the energy lost can be negligible. These collisions can be considered elastic, even though they are not perfectly elastic. Collisions of rigid billiard balls or the balls in Newton's cradle are two such examples.
The correct answer is 40.5 Newtons just finished the quiz and 36.5 was incorrect.
