Question

Find an equation for the minimum coefficient of state of static friction that will allow a piece of clothing to remain stack to the inside wall of the drum, without sliding and toward the bottom of the tab. Show your work. A roller consider ride contains a point vertical loop a circle of radius 8.50 m. What I the minimum speed required at the top of the loop so that passengers will stay in contact with their ?Show your work. Suppose a 50.0 kg passenger rides the roller contact car through the top of the loop so that passengers will stay in contact with their seats normal force then her seat? What percentage of her weight is this? Show your work.

Explanation / Answer

4.)a.)

What is the minimum speed required at the top of the loop so that passengers will stay in contact = sqrt(g*R)

V = sqrt(9.81*8.5) = 9.13 m/s

b.)magnitude of the normal force from her seat = Mv^2/R - Mg

N = 50*11*11/8.5 - 50*9.81 = 221.26 N

%of weight = 221.26*100 / (50*9.81) = 45.11 %
