Guys, does anyone know the answer?

In a lab, a block weighing 80 N is attached to a spring scale, and both are pulled to the right on a horizontal surface. Friction between the block and the surface is negligible. What is the acceleration of the block when the scale reads 32N?

do you mean, "what would the acceleration be if the block were relased when the scale reads 32N?"

one second and i'll help ya...

are you guys working with conservation of energy right now or forces? just so I can answer in the right terms for you.

forces

k, recall that F = mass * acceleration? and that 80N = mass * 9.81? and that Spring Force 32N= k*x?

I still don't get how i'd incorporate 32N

So the 32N helps us figure out how much force is being applied to the block that weighs 80N (which is 8.15kg)

Okay, thank you so much for the help!!

hint - the acceleration should be between 2 and 4 if you did it correctly (and if I understnd it correctly!)

yah, i got 4, thnks again

boo ya!
