Question
Please answer part (d) & part (e) super fast
A 2.12 kg friction-less
4.
block is attached to a horizontal spring as shown.
Spring constant k = 206.12 N/m. At t = 0, the
position x = 0.225 m, and the velocity is 4.25 m/s
toward the right in the positive x direction.
Position x as a function of t is x = A*cos (wt + 0),
where A is the amplitude of motion and w is the
angular
e is called the phase constant that will
also be addressed below.
Use conservation of energy to
(a)
compute amplitude A.
(b)
How much farther from the point
shown will the block move before it momentarily
comes to rest before turning around
(c)
What is the period T of the
motion?
(d)
If the mass of this problem was
doubled to 4.24 kg, how would your answer to
part (c) change?
(e)
to find phase constant .
