1. The problem statement, all variables and given/known data A rock initially at rest in a sling of length r meters is brought to a speed of n rotations per second after three complete revolutions. It is then released , leaving the sling at an angle of θ above horizontal. When the rock is released, write the initial velocity and its horizontal and vertical components in terms of the variables provided above given equation: https://gyazo.com/1541ea407be0853d58465bed8abc9c82 my question is isn't the Accel tan of whn the sling is release = Vi? if not, why and how can I get the Vi?
