Question

What is the mechanical energy of a oscillation? the block postion x=11cm,speed v=0 and spring constant=65Nm​

Answer 1

Answer:

Mechanical energy of a oscillation is 0.39 J

Explanation:

Mechanical Energy of any Oscillator ∝ A²

Here , A = Amplitude

k = 65 Nm

v = 0

m = Not given

x =  11 cm = 0.11 m

Mechanical Energy of an Oscillator = Potential Energy + Kinetic Energy

                                                             = (kx²)/2 + (mv²)/2

                                                            = (65*11/100*11/100)/2 + (m*0*0)/2

                                                             = (65*0.11*0.11)/2 + 0

                                                             = 0.7865/2

                                                             = 0.39325 J

Here,

k = Spring Constant

x = Length

m = Mass

v = Speed

J = Joule
