Question

@mathmale if you exert a force of 700N to walk 6 m up a flight of stairs in 6 s, ho much power do you use?

Answer 1

Power is "rate of doing work." If we were to express power in the metric system, I believe the correct units of measurement would be joules/sec. But you'd better double-check this.

If power is "rate of doing work," then we'll need to calculate the ratio (amount of work done) / (amount of time required to do that work).

Does this info give you enough info to get started?

Answer 2

No, but you are correct .

Answer 3

Given FORCE and DISTANCE over which the force moves an object, what is the WORK done?

Answer 4

Work = ( ? )*( ? )

Answer 5

my choices are
A : 19W
B: 4,200W
C: 25,200W
D: 700W

Answer 6

@mathmale

Answer 7

Nick: Work = ( ? )*( ? ) I trust you know the definition of "work" and would like for you to fill in the unknown quantities in this equation.

Answer 8

@mathmale

Work=FD right?

Answer 9

Yes. You are given F and also the distance, D.
Calculate the amount of work done by multiplying those two together.
Work done= ??

Answer 10

sorry for the delays, but OpenStudy is being heavily used right now and response time correspondingly slow.

Answer 11

so muiltiply the two numbers

Answer 12

Please take the given info and do that multiplication.
