Physics
A loaded penguin sled weighing 73 N rests on a plane inclined at angle θ = 21° to the horizontal (Fig. 6-23). Between the sled and the plane, the coefficient of static friction is 0.24, and the coefficient of kinetic friction is 0.19. (a) What is the minimum magnitude...

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 = change in KE = .5mv^2f...
