Homework Statement
A flywheel with a radius of 0.200 starts from rest and accelerates with a constant angular acceleration of 0.900 .
atan= .180 m/s2 when its at rest
arad= 0m/s2 when at rest
compute magnitude of resultant acceleration at the start a= .180 m/s2
I got all of these already...
well using the information that you gave which is not very clear.
Your freebody diagram would be:
mg acting downward on the 1000kg block and Tension (T) acting upward on the block
Thats just for the block.
There are no foces acting in the X axis
ƩFy=o=T-mg (this is the sum...
use this after you get the numbers from momentum equation of:
ƩPi=ƩPf
(you have the break down of the above correct?)Now plug into this
0=ΔKE+ΔPEg+ΔPEspring
=1/2mv2f-1/2mv2f+mghf-mghi+1/2kx2f-1/2kx2f
Now just place you values in the equation and remove things that you don't use for example...
