If a rock hits the ground with a KE of 33000 J falling from a height of 10 m what is its weight?
337 Kg
What energy changes occur when a falling rock hits the ground?
Kinetic Enegry
How does the height of a ball affect the height of its bounce?
the potential energy gets changed into kinetic energy so when it hits the ground it will bounce back up.
How can you calculate wasted energy from a falling object when given only height and mass?
Because gravitational potential energy is defined by g*m*h where g is the gravitational constant 9.8, m is mass, and h is height. With just height and mass, you cannot calculate "wasted energy" by which i assume you mean energy lost to air resistance. However, if you are given the kinetic energy of the object just before it hits the ground, then you calculate the total energy before falling and compare it to the kinetic energy right before hitting the ground. the difference would represent the energy lost to air resistance
Why it is dangerous to jump from significant height?
Falling from a significant height will add more momentum to the falling object and according to one of the laws of gravity, an object in motion tends to stay in motion unless acted upon by another force, so once the falling object hits the ground the momentum will try to go through the ground but the falling object will hit the ground pretty forcefully. Also why am I here I have to study for exams

How the total energy changes when a falling rocks hits the ground?
adolf Hitler is amazin ;)
Which type of precipitation is made when falling snow melts and then freezes again before it hits the ground?
sleet
How does the total energy change when when a falling rock hits the ground?
when the rock falls it gain kinetic energy when it falls.
When an egg hits the ground does it have friction?
the height of an object has more POTENTIAL ENERGY.Converted to kinetic energy

If a ball is dropped from a height of 100m each time it hits the ground it bounces 3 5ths of the height it fell How far will the ball have traveled in the 5th bounce?
89
