Tarzan swings on a 40m long vine intially inclined at an angle of 40 degrees with the vertical. Acceleration of gravity = 9.81 m/s^2. What is his speed at the bottom of the swing if he starts from rest?
i started by drawing a diagram. and then i used trig to find the distance between the...
a small ball of mass 38g is suspended from a string a length 59cm, and whirled in a circle lying in the horizontal plane. The acceleration of gravity is 9.8m/s2. if the string makes an angle of 31o with the vertical, find the centripetal froce experienced by the ball.
here's the diagram:(the...
finding friction coefficient without a mass??
A box slides down a 37.1o ramp with an acceleration of 1.29m/s2. (acceleration of gravity is 9.8m/s2) Determine the coefficient of kinetic friction between the box and ramp.
I just have no idea where to start with this since it doesn't give...
