Answer:

See below ~

Step-by-step explanation:

<u>Change in KE if mass is doubled</u>

  • KE (original) = 1/2mv²
  • KE (new) = 1/2 x (2m) x v²
  • KE (new) = mv²
  • ⇒ <u>KE is doubled</u>

<u></u>

<u>Change in KE if speed is doubled</u>

  • KE (new) = 1/2 x m x (2v)²
  • KE (new) = 1/2 x 4 x mv²
  • KE (new) = 2mv²
  • ⇒ <u>KE is quadrupled</u>

Solve and check:8a-4=25+6(a-8)
OlgaM077 [116]
8a - 4 = 25 + 6 (a - 8)

(distribute the 6)

8a - 4 = 25 + 6a - 48

(combine like terms 25 - 48)

8a - 4 = 6a - 23

( subtract 6a from both sides)

2a - 4 = -23

(add 4 to both sides)

2a = -19

(divide both sides by 2)

a = - 9.5

////CHECK/////

8 (-9.5) - 4 = 25 + 6 ( -9.5 -8)

(plug each side into a calculator)

-80 = -80

FINAL ANSWER:

a = -9.5
