Lets say we had a pendulum mass M, Length L, and distance from 0 of X (0 is the middle, where angle Z= 0) If we let it go from a certain point, then the force upon it would be F= Mg[sinZ] (note, using Z instead of theta for the angle made by the pendulum and vertical in radians) Then Ma= Mg[sinZ] So a=g[sinZ] -- a=g[sin{X/L}] (radians arc ...

Maribat tumblr11)A 22 kg mass is connected to a nail on a frictionless table by a (massless) string of length 1.3 m. If the tension in the string is 51 N while the mass moves in a uniform circle on the table, how long does it take for the mass to make one complete revolution? A)4.7 s B)4.4 s C)3.8 s D)5.1 s 11)

A thin circular ring of mass M and radius R is rotating about its axis with a constant angular velocity ω . Two objects, each of mass m are attached gently to the opposite ends of the diameter of the ring. The wheel now rotates with an angular velocity. (A) ω M/ (M + m) (B) { (M – 2m)/ (M +2m)}ω. (C) {M/ (M + 2m)}ω.
