Question

In the oscillating spring ball system, where is the velocity of the ball the greatest?

Select the correct answer:
O The velocity is the same everywhere.
O At the equilibrium point.
O At the turning points.

Answer 1

The speed of an object in a mass-spring system is given under the function

`v = \pm \sqrt{(k)/(m)(A^2-x^2)}`

Here,

m = mass

k = Spring constant

A = Amplitude

x = Position

When the position is at the equilibrium point (x = 0), the speed will be maximum, and could even be expressed as

`v_(max)= A\sqrt{(x)/(m)}`

So the correct answer is B.
