Question
the height is at h = 5r, and the loop has a radius r.
a.) calculate the speed of the mass at the bottom of the looped track
b.) the normal force to the mass from the track at the bottom of the loop
c.) the speed of the mass at the top of the loop
d.) the normal force on the mass from the track at the top of the loop
-----------------------PLEASE PROVIDE A STEP BY STEP AND EXPLANATION FOR EACH VALUE, ESPECIALLY FOR PARTS C AND D.
the answer key states for part c, that v_1 = 0, v_2 = 0, and y_1 = 3gr.
why is that?
Explanation / Answer
a)conserving energy, mgh = .5mv^2 so, v = sqrt(2gh) = 9.9*sqrt(r)Related Questions
