A small ball is hung as shown an a string of length L. (a) If `v_(0) gt sqrt(6 g l)`, find the angle `theta ( lt 90^(@))` [in terms of, `v_(0), g, L`] with the upward vertical at which the string becomes slack. (b) find the value of `v_(0)` [ in terms of g, L] if the particle passes through point of suspension img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/EAM_MEC_V01_C03_S01_041_Q01.png" width="80%"
