Answer: its is you figer it out okay haha

Step-by-step explanation: im jokeing

Kinetic energy = 1/2 M V2

At the lower speed, the car's KE is (500) (1)2 = 500 joules

At the higher speed, the car's KE is (500) (2)2 = 2,000 joules

The difference is the energy i.e. the work you have to put into it

to raise the speed from 1 m/s to 2 m/s.

(2,000 - 500) = 1,500 joules there u go :D

This is a combination since the order doesn't matter
C(15, 6) = (15 * 14 * 13 * 12 * 11 * 10)/(6 * 5 * 4 * 3 * 2 * 1)
C(15, 6) = 3603600/720

Bot 2 will click more times in 10 seconds, because when you divide 16 by 2 to get its unit rate it is 8 clicks per second. Times that by 10 and you only get 80, whereas if you divide 30 by 3 the unit rate is 10. At this rate, by 10 seconds it will have clicked 100 times. Bot 2 clicks 20 more times than Bot 1 in 10 seconds.
