Question

m = 0.3kg, A = 0.1m, T = 0.5s, k = 47.4 N/m
w = 12.57 rad/s, E = 0.237 J
e. What is velocity at 0.05m?

Answer is 1.09 m/s. How do I solve this?

science physics

Answer 1

Answer #1

Total mechanical energy = 0.237 J

Energy is conserved therefore,

0.237=oT2

47.4 * 0.05 0.237 -- 0.3 + u 一十

Solving we get,

v = 1.088 m/s 1.09 m/s
