1,000 J

50 J

500 J

250 J

Answer 1

I posted this in the other question lol

\[K.E = \frac{ 1 }{ 2 } m v^2\]

Answer 2

just saw what you typed

Answer 3

:) no problem

Answer 4

250

Answer 5

correct!

Answer 6

another question
If you apply 100.0 N of force to lift an object with a single, fixed pulley, then what is the resistive force?

Answer 7

hmm, not too sure about that one....I'm going to say that only the force of gravity is the resistive force since it is the only force acting opposite to the lift...not too sure on that (what are the choices?)

Answer 8

200.0 N

100.0 N

50.00 N

10.00 N

Answer 9

okay i asked a new question
