PLEASE HELP I NEED TO FINISH THIS TEST I HAVE 20 MINS HELP ASAP A ball rolling on a smooth horizontal floor strikes an identical ball and comes to a stop. The second ball starts moving at a speed slightly slower than that of the first ball before it came to a stop. A graph showing the kinetic energy of the first ball over time is shown
below.
Kinetic Energy Over Time
Kinetic Energy (1)
1-
0
Time (s)
Why did the first ball come to a stop on collision?
OA. Its kinetic energy was destroyed and permanently lost from the system during the collision.
ОВ.
Its kinetic energy was converted to thermal energy and the potential energy of the second ball during the collision.
OC. Its kinetic energy was completely lost to the surrounding environment as thermal energy during the collision.
D. Its kinetic energy was converted to thermal energy and the kinetic energy of the second ball during the collision.

Hot air balloons float in the air because of the difference in density between cold and hot air. in this problem, you will estimate the minimum temperature the gas inside the balloon needs to be, for it to take off. to do this, use the following variables and make these assumptions: the combined weight of the pilot basket together with that of the balloon fabric and other equipment is w. the volume of the hot air inside the balloon when it is inflated is v. the absolute temperature of the hot air at the bottom of the balloon is th (where th> tc). the absolute temperature of the cold air outside the balloon is tc and its density is ďc. the balloon is open at the bottom, so that the pressure inside and outside the balloon is the same. as always, treat air as an ideal gas. use g for the magnitude of the acceleration due to gravity.
