A rock of ma m = 0. 52 kg i attached to a male tring of length L = 0. 79 m. The rock i wung in a vertical circle fater and fater up to a peed of v = 4. 8 m/, at which time the tring break. Thi occur when the tring i horizontal a hown in the figure A. What i the magnitude of the tenion, in newton, at which the tring break? and B. How high, in meter, doe the rock travel? Ue a value of h = 0 at the location of the break
