Question

If the 10-lb block passes point A on the smooth track with a speed of ,determine the normal reaction on the block when it reaches point B.

I already solved this problem and ended up with a final answer of N= 20.48 lbs. My question is "How would the problem be different if the block was moving up the incline surface instead of down?"

Explanation / Answer

its 20.5lb. Radius of curvature is 16. N-W=(W/g)(V^2/P) N-10=(10/32.2)(23.24^2/16) N=20.5

V from Wh+(1/2)(W/g)(Vinitial)^2=(1/2)(W/g)(Vfinal)^2
