The height, h to which the package of mass m bounces to depends on its initial velocity, v and the acceleration due to gravity, g and is given below:
<h3>What are perfectly elastic collision?</h3>
Perfectly elastic collisions are collisions in which the momentum as well as the energy of the colliding bodies is conserved.
In perfectly elastic collisions, the sum of momentum before collision is equal to the momentum after collision.
Also, the sum of kinetic energy before collision is equal to the sum of kinetic energy after collision.
Since some of the Kinetic energy is converted to potential energy of the body;
Therefore, the height to which the package m bounces to depends on its initial velocity and the acceleration due to gravity.

The formula for working out kinetic energy is
=122
KE = kinetic energy
m = mass of a body
v = velocity of a body
kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.
For the first one I think :
Answer:
KE = 330750 J
I’m not sure about the second one- sorry
The third is
Answer:
KE = 41454 J
Hope it helps and it is correct, sorry if it isn’t !
Answer:
One reason is the positioning of the earth on its axis. The sun doesn't hit where we live in winter because we are pushed upwards more so we don't get the suns heat. The sun goes down earlier... so we don't have as much sunlight.
In winter the sun is father away from earth and in Summer it is closer...
Explanation:
Using a machine can speed up work very quickly as machines are way faster than humans. Machines also do not get exhausted unlike humans so can work over a long period of time non stop.
Diamonds are supposed to formed about 90 miles below the surface of the earth in the mantle. Therefore, the weight of the earth overhead them produces the pressure to form the diamond. The rocks weight overhead the mantle outcomes in high pressure and diamonds essential high temperatures and pressure to form as of carbon.Diamonds form in the mantle in definite precincts where situations are right for them to do so. There just chances to be the right critical temperature-pressure-mineral environment in the mantle in definite areas for their formation.
