Given :
A 0.50-kg mass is attached to a spring of spring constant 20 N/m along a horizontal, frictionless surface.
The object oscillates in simple harmonic motion and has a speed of 1.5 m/s at the equilibrium position.
To Find :
At what location are the kinetic energy and the potential energy the same.
Solution :
Let, at location x from the equilibrium position the kinetic energy and the potential energy the same.
So,
Hence, this is the required solution.
Explanation:
<h2>Speed is the rate of change of distance with time.</h2>
You need to use snell’s law in this problem. N1sin (theta) = n2sim (theta)
N1 = index of oil
N2 = index of glass
If you already have the numbers, include it in this
equation:
N1.sin (90deg) = N2.sin (critical angle) (note sine (90deg)
= 1)
