A student lifts a 1.5 kg textbook a distance of 2.5 m vertically. How much work does she do?
W=Fd
How do I use the mass to find force?
Work Force is how much force you put in work :science:
You're finding force times distance, which is work. Hint, force is m*g.
Hint: f=ma

Hey, if I were to start a physics group on FP would you join?
help out some people at your leisure?
work = force x distance
work = joules
force = newtons
distance = meters
power = work / time
power = joules (as a rate)
work = joules
time = second
f = ma
force = newtons
mass = kilograms
acceleration = m/s2 or m/s/s
I thought Joules was a unit of temperature?

You just copy and pasted those equations didn't you?

If you pa[b]id[/b] attention to your science teacher you might learn something.
Amazing isnt it
happy spellfag?

If you paid attention to your English teacher, [I]you[/I] might learn something.
Amazing, isn't it?

If you realized that all they do for us now is slap a novel and corresponding quiz on our desk, you might not make shitty comebacks.
Also, wow I missed one word whilst typing in a haste manner to get back to a game more important than this thread, are you gonna make a joke about it?
Keep the box, store your awful 34k posts in it

Lower case g is gravity in the direction of the source in most cases, so that would be weight.
I wanna go to Knott's again...:unsmith:
Good times.
W = 1.5 d = 2.5
W = fd.
f = W/d
f = 1.5 / 2.5
f = 0.6
It depends what level you're at. If all the information you got was W = df this should suffice.

mass = 1.5, not work. Work is energy required, read the OP
you need to do mg to find F
Thats mass x g (g is 9.81...)
so w=1.5x9.81 x 2.5
Urgh, even simple Physics equations fuck me up.

Looks like the [i]work done[/i] by the OP is 0. :smug:
