i guess it was the plane mirror one bcoz i got that wrong 2kamihus
do u remember what was Q25?
ok dude i know alreadydude for 14. not small size....plane mirror produces exact same size image...the asnwer was virtual and not inverted....
and it was GPE To Kinetic+thermal, not gpe to kinetic to thermal
The person slowed down which meant kinetic energy was being converted into heat energydude for 14. not small size....plane mirror produces exact same size image...the asnwer was virtual and not inverted....

yeah the person was slowing down.........now how can it be converting to kinetic when he was slowing down..........i also wrote kinetic+g.p to thermalThe person slowed down which meant kinetic energy was being converted into heat energy

What no. It was GPE --> KE--> TEMy point exactly. The kinetic energy was decreasing as he was going down, which means that he was losing kinetic energy. The only form of losing the kinetic energy was heat so it should have been G.P.E + K.E --> Thermal Energy.
Now, if his G.P.E was being converted to K.E and Heat Energy, why would he slow down? He would either speed up or maintain a constant speed.
What no. It was GPE --> KE--> TE
As he was falling into the pool, he was gaining kinetic energy. At the highest point, his kinetic energy was 0 and PE was maximum. As he was falling, that PE was being converted to kinetic energy. But due to air resistance or something his KE was converted to heat energy. As a greater amount of kinetic energy was being converted to heat energy, he slowed downOk, if G.P.E. was being converted to K.E. first then why did he even slow down? Wouldn't he remain at the same speed?

Plus where did the kinetic energy come from in the 1st place then,
Ya so he was gaining kinetic energy as he was falling. At the top of the plank, his KE was zero as I've mentioned already, so his PE had to convert into KEDidn't they mention that already? That he was swimming down at a great speed and eventually slowed down by the bottom of the pool?

yes it was mentionedI don't exactly remember but I think it was mentioned that he was travelling at his greatest/maximum speed.
Yeah so? I never said it wasn't...but the question also alluded to the fact that he fell from a plank or something..I remember it made a reference to how his PE was maximum at the top and that he had no kinetic energy AT THE STARTI don't exactly remember but I think it was mentioned that he was travelling at his greatest/maximum speed.

i think the question was about the energy change as he was falling.............not the overall change...can anyone confirm? if yes than he had both K.E and G.P at the startWhen he jumped off the plank, didn't he have K.E. Energy?
My point exactly. The kinetic energy was decreasing as he was going down, which means that he was losing kinetic energy. The only form of losing the kinetic energy was heat so it should have been G.P.E + K.E --> Thermal Energy.
