PHYS 2101 Lecture 7: PHYS 2101 7

Hello, I need Some Help for this Problem..

Someone con Help Me?
a collar that slides along a horizontal rod has a pin thatisrequired to move through the slot in the arm AB. the armswingswith an angular position given by θ (t) = 90-30 cos (t)whereθ(t) is expressed in degrees and T in seconds.

T = 5sec:

a) determine the radial distance r (t)
b) identify the components of velocity VR (t) and Vθ (t)
c) determine the components of the acceleration Ar (T) andAθ(t).

d) verify that the velocity and acceleration vectorsaredirected along the rod horizontal
