a) F = ma |F| = 84kg*-3.5m/s^2 b)v=0 x= -(41m/s)^2/(2(-3.5m/s^2)) c)W is going in the -x direction because it's decelerating W= -Fd Then you just apply these equations to d,e, and f.

m=1kg L=.56m change in KE + change in PE = E .5mv^2f + mghf = .5mv^2i + mghi Even though this problem is a circle, the height variable in the potential energy equation shouldn't differ. a)Use the bottom of the circle for h=0 mghi is canceled. work = chang...

^^^^drwls How did you get 167 - 151 = 46???

The answer is clearly 1x11. It is 1x11 because 11+1+11+1=24, 2(12)=24. And is the longest possible way of doing so.
