Answer:
d) The stone will have about 50 joules of kinetic energy and 0 joules of potential energy .
Explanation:
Given :
Initial Potential energy ,
.
Initial Kinetic energy ,
. ( because ball is in rest )
Now , we know , kinetic energy is maximum when an object reaches ground .
Also , potential energy is zero when an object is in ground .
We know , by conservation of energy :
Initial total energy = Final total energy

Therefore , option d) is correct .
Answer: 3,893,845.918 Ping-Pong balls
Explanation:
The volume of an average room is:
(1)
(2)
Now let’s transform this
to units of
, knowing
:
(3)
On the other hand, we have Ping-Pong balls with a radius
, and their volume is given by:
(4)
(5)
(6)
Now, the number
of Ping-Pong balls that can be packed into the room is:
(7)
(8)
This is the number of Ping-Pong balls that can be packed into an average size room
