Given:
E W
So,
E = kW where k is some constant .
Given E = 2
When W = 23
So,
2 = k * 23
k = 2/23
So, we have now formula
E =
Putting W = 18 in above formula:
E = ,
E =
Answer:
E = when W = 18.

Please Hand write the answer and show which equations are used. Thanks! A mass-spring system (m = .50 kg, k = 1200 N/m) is given an initial compression of .05m. The system then oscillates horizontally on a frictionless surface. Calculate the following: (a) the initial potential energy of the system (b) the maximum kinetic energy of the system (the KE varies with time, but what is the maximum it can be?) (C) the maximum velocity? (d) the angular frequency, w,...

Review Constants Let's begin with a straightforward example of simple harmonic motion (SHM). A spring is mounted horizontally on an air track as in (Figure 1), with the left end held stationary. We attach a spring balance to the free end of the spring, pull toward the right, and measure the elongation. We determine that the stretching force is proportional to the displacement and that a force of 60 N causes an elongation of 0.030 m. We remove the spring...
Please answer this for me completely. I need the help. The position of an object connected to a spring varies with time according to the expression x = (4.7 cm) sin(7.9 pi t). (a) Find the period of this motion. s (b) Find the frequency of the motion. Hz (c) Find the amplitude of the motion. cm (d) Find the first time after t = 0 that the object reaches the position x = 2.6 cm. s
