Please help with 7-8 of this fbd worksheet on circular motion. Please include the fbd, center, equation, forces, and radial and tangential or perpendicular axes.

Transcribed Image Text:8. The cylindrical drum in (7) has speeded
up and the floor has dropped down
Fc =.
7.
person standing in the rotating
drum of an amusement park ride
Fc =
A roller coaster cart passing through
the bottom of a circular dip in the track
Fc = E Fg
10. A ball inside a frictionless circular loop,
at the highest point
Fc=tFa
%3D

Transcribed Image Text:7-3 Free-body Diagrams for Circular Motion, Part 1
For each situation 1- 10, follow the steps below to write the equation for Fc
• Identify the object, its circular path, and the center of the circle.
Draw the free-body diagram (FBD).
DO include all forces that act on the object.
DO NOT include forces the object exerts on its surroundings.
Sketch the radial (±r) and the tangential (±t) or perpendicular (±p) axes on the FBD.
The radial axis, r, points from the object to the center of the circle.
Radially inward is the +r direction. Radially outward is the -r direction.
Write an equation for Fc in terms of the forces acting on the object. For example,
Fc= Fg - FN.
1. A yo-yo on a string, circling into the
page on a flat, frictionless surface
2. A cart moving at constant speed over
the top of a circular hill
Fc=EE
Fc= F
