Question

You move a 75-kg box 35 m. This requires a force of 90 N. How much work is done while moving the box?

A. 1,500 N
B. 165 N
C. 125 N
D. 3,150 N

Answer 1

pwease help? (:

Answer 2

D

Answer 3

D

Answer 4

Hmm so i am gonna say D... ? :D :D lol

Answer 5

Force = 90N
Distance = 35m
\[Force \cdot Distance = Work = (90 \cdot 35)J = 3150J\]

Answer 6

None of the above is correct because they are all listed in Newtons which is not a unit of work.

Answer 7

Ah, alright.
So then

Which of the following is required for work to be done on an object?

A. In order for work to be done the object must move in the direction of the force and rotate.
B. In order for work to be done the object must move over a distance opposite the direction of the force.
C. In order for work to be done the object must not move at all.
D. In order for work to be done the object must move in the direction of the force and move over a distance.

B or C ? (:

Answer 8

Neither.

Answer 9

ohhh wait.. but your not thinknig Joules are you? Because

Answer 10

It said like 55 n -m still equals 55 joules :P If that example makes sense

Answer 11

In order for work to be done the object must move in the direction of the force for some distance.

Answer 12

Yes, but you listed the answers as "D. 3,150 N" which is not a \(N\cdot m = J\)

Answer 13

Hmm right. Well thats odd.. i copied and pasted my question >.<

Answer 14

Then your worksheet is wrong, or a trick question ;p

Answer 15

Hmm
Prolly a trick question >.< I hate those ;P
Thanks though (:

Answer 16

Probably just the teacher typed it wrong.

Answer 17

Yea most likely >.<

Answer 18

Anyway, the answer to your most recent question is D. There must be a force in the direction the object is moving, and (obviously) the object must move.

Answer 19

Yes, i had gotten that (: You had given me the answer... even though you hadnt said the letter :D Im not too daft to see that ^_^

Answer 20

Oh, well you hadn't clicked 'good answer' so I wasn't sure if you understood what I meant. ;p

Answer 21

Haha I need to stop doing that just because the person answers my question... ^_^
No i understood perfectly (:
