A small block with mass 0.0475 kg slides in a vertical circle of radius 0.0730 m on the inside of a circular track. There is no friction between the track and the block. At the bottom of the block's path, the normal force the track exerts on the block has magnitude 3.70 N. What is the magnitude of the normal force that the track exerts on the block when it is at the top of its path?
Homework Answers
Velocity, v = sqrt(0.073 x (3.7 - (0.0475 x 9.8))/0.0475) = 2.23 m/s
Using law of conservation of energy,
Vf = sqrt[2.23^2 - 2 x 9.8 x (2 x 0.073)] = 1.45 m/s
Force, N = (0.0475 x 1.45^2/0.073) - (0.0475 x 9.8) = 0.90 N

Circular motion, vertical surface with kinetic friction: A small block of mass 2.0 kg slides on a horizontal frictionless surface as it travels around the inside of a hoop of radius R 0.50 m. A view from above is shown. The coefficient of friction between the block and the hoop wall is 0.20. Therefore, the block is slowing down. a) Draw a free body diagram for the block in the position shown (you do not need to include forces perpendicular...

A rollercoaster cart with a mass of 11 kg is travelling around a
vertical loop (circle) with a radius of 8 meters. At the top, it's
traveling at the minimum speed needed so that it remains in contact
with the track. If at some short time later it is at the side of
the loop (halfway between the top and bottom), what is the normal
force on the cart, in Newtons, if it loses 147 Joules of work to
