    Tarzan's velocity while swinging on his vine

    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...

    How Do You Calculate the Centripetal Force of a Whirling Ball?

    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...

    How to Find Friction Coefficient Without Mass?

    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...
