A mass is oscillating with amplitude A at the end of a spring. How far (in terms of A) is this mass from the equilibrium position of the spring when the elastic potential energy equals a half the kinetic energy?
Ac = v^2/r = 18.2^2/120 = 2.76 m/s^2 at ≡d |v|/dt= 2.99 m/s2 sqrt(2.76^2+2.99^2)=4.069 m/s^2 μs=(|a|max)/(g)=4.069/9.8=.4152
