1- if you decrease the hanging mass by a factor of four( 0.55 kg/4) but keep the linear mass density the same, by what factor does the fundamental frequency change. Explain using equations. .2-if you decrease the linear mass density by a factor of four, but keep the hanging mass same, by what factor does the fundamental frequency change. Explain using equations.
A particle moves along the x-axis according to the equation x(t) = 2.0 + 3.0t2 - 1.0t3, where x is in meters and t is in seconds. What is the position of this particle when it achieves its maximum speed in the positive x-direction? What is its spe..
