Not sure...I did: PE=m*g*h
--> .25*9.8*5 = ~12.5, but that's the same as what I got for B!?
Also, could you possibly help clarify the "how high does the ball go?" aspect of the 2nd question?
Sorry, thanks for your response!
I'm completely stuck on 1a, but for 1b I converted the grams to Newtons so..
w=f*d
w=2.5*5
w=12.5 J (but I'm not sure)
again, c confuses me a lot
for 2a, I did
w=15*.05=.75 J, but I'm not sure where to go from there!
Hey everyone, I'm really lost with my physics homework!
A ball of mass 250 g is dropped 5 m onto a spring
-how much KE wil the ball have when it hits the spring?
-how much work will be done as the spring is compressed?
-If the spring is 250 kN/m, calculate how far the spring will be compressed...
