Apumpkin was dropped from a balcony of a skyscraper. the pumpkin happened to land on a sidewalk force sensor and the below data was collected.
after collecting all of the pumpkin gore, you determine that the pumpkin was 2.7kg in mass.

a) from what height was the pumpkin dropped?

b) from what floor of the skyscraper was the pumpkin probably dropped?

a. Any Height  

b. Any floor other than the ground floor.

Explanation:

For a fallen object

PE(potential Energy) = KE(Kinetic Energy)

therefore  

In this case only a change in form of energy was witnessed.

According to law of conservation of mass, " states that mass can neither be created nor destroyed"

Mass is conserved over time despite change in form, Mass quantity is neither added nor removed.

Since all pumpkin gore was collected and weighed.

At any known height

M_b(mass before drop)=M_a( mass after drop)

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
