If a toy helicopter is moving at 12 m/s, how much energy does 3kg toy have?

9514 1404 393

  216 J

Step-by-step explanation:

The kinetic energy is given by ...

  KE = 1/2mv^2

  KE = (1/2)(3 kg)(12 m/s)^2 = 216 kg·m²/s² = 216 J

The kinetic energy of the toy is 216 joules.

__

Its potential energy depends on its height.

answer: 19 is   2

step-by-step explanation: i just looked at your answer and wrote it down

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
