Question

Tarzan begins to swing from a height h on a vine of radius R. (a) If R= 8.16m and h=3.87 m, find the angle the vine makeswith the vertical. (b) draw the acceleration vector due to earths gravitationalattraction on Tarzan directly on the figure to theright. (c) Find the magnitude of the projection of the accelerationvector g, onto R and perpendicular to R. Call these Ar andAt. (a) If R= 8.16m and h=3.87 m, find the angle the vine makeswith the vertical. (b) draw the acceleration vector due to earths gravitationalattraction on Tarzan directly on the figure to theright. (c) Find the magnitude of the projection of the accelerationvector g, onto R and perpendicular to R. Call these Ar andAt.

Explanation / Answer

if be the angle made by the rope withverticle           cos = x / R             x = R cos . height from the ground             h = R- x                  =R - Rcos                 =R(1-cos) the acceleration due to gravity parelle to rope           Ar= mg cos            At= mg sin.
