Hi
I attempted the question and got the wrong answer
A Block Of Mass M Is Undergoing SHM On A Horizontal, Frictionless Surface While It Is Attached To A Light, Horizontal Spring That Has Force Constant K. The Amplitude Of The SHM Of The Block Is A. What Is The Distance |X| Of The Block From Its Equilibrium Position When Its Speed V Is Half Its Maximum Speed Vmax? Express In Terms Of A Is This Distance Larger
A block of mass m is undergoing SHM on a horizontal, frictionless surface while it is attached to a light, horizontal spring that has force constant k. The amplitude of the SHM of the block is A.
What is the distance |x| of the block from its equilibrium position when its speed v is half its maximum speed vmax? Express in terms of A
Is this distance larger or smaller than A/2?
I started by setting ek=ep
then I substituted for vmax into Ek
I isolated for x and got a/2 not sqrt3/2
what is the right way to go about this question?
