What is the tangential speed of the ball?
A 0.700 kg ball is on the end of a rope that is 3.10 m in length. The ball and rope are attached to a pole and the entire apparatus, including the pole, rotates about the pole’s symmetry axis. The rope makes an angle of 70.0° with respect to the vertical as shown. What is the tangential speed of the ball?
this is counterbalanced by the horizontal component of rope tension:
m*g*sin(70)
r=3.1*sin(70)
So here’s the result
using g=9.81
v=sin(70)*sqrt(3.1*9.81)
v=5.18 m/s
