1. The problem statement, all variables and given/known data A rock of mass m=2kg is tied to a string of length r=4m is rotating at a constant rate and subject to a centripetal force Fc=32N. Find the: a)Centripetal acceleration b)Angular velocity c)Angular momentum 2. Relevant equations a) Ac=V2T/R (Fc=V2T/R; so, V2T=Fc x R/m?) b) VT=angular velocity x radius c) l = mvTr 3. The attempt at a solution a) 32 x 4/2 = 64[m2/s] b) V2T = 64, so VT = 8; 8/4 = 2 [rad/s] c) 2 x 8 x 4= 64[kg x m2/s] I know this is simple stuff, but I'm new to physics, and just wanted to double-check that I'm getting my formulas right. Thanks everyone!
