As a pendulum swings back and forth, its total energy is 16 J. What is its potential energy at 3/4 its maximum height?

Respuesta :

Let height h go from 0 ⇒ 1:
[tex]E = E_k_i_n + E_p_o_t = 16[/tex]

at h = 3/4:

[tex]E = \frac{1}{4} E_k_i_n + \frac{3}{4} E_p_o_t = 16 \\ \\ E = 4 + 12 = 16 \\ \\ E_k_i_n = 4J \\ \\ E_p_o_t = 12J[/tex]
