2.
Multiple Choice
What combination of values will result in a spring - block system with the greatest frequency?
A = 50 cm; k = 80 N/m; m = 2 kg
A = 50 cm; k = 100 N/m; m = 2 kg
A = 50 cm; k = 100 N/m; m = 4 kg
A = 75 cm; k = 80 N/m; m = 2kg
A = 75 cm; k = 100 N/m; m = 4 kg

Multiple Choice
A block attached to an ideal spring undergoes simple harmonic motion about its equilibrium position (x = 0) with amplitude A. What fraction of the total energy is in the form of kinetic energy when the block is at position
(x =1/2 A)?
1/3
3/8
1/2
2/3
3/4
4.
Multiple Choice
A linear spring of force constant k is used in physics lab experiment. A block of mass m is attached to the spring and the resulting frequency, f, of the simple harmonic oscillation is measured. Blocks of various masses are used in different trials, and in each case, the corresponding frequency is measured and recorded. If f2 is plotted versus 1/m, the graph will be a straight line with slope
4π2/k2
4π2/k
(4π)(2k)
k/4π2
k2/4π2

Multiple Choice
A block of mass m = 4 kg on a frictionless, horizontal table is attached to one end of a spring of force constant k = 400 N/m and undergoes simple harmonic oscillations about its equilibrium position (x = 0) with amplitude A = 6 cm. If the block is at x = 6 cm at time t = 0, then which of the following equations (with x in centimeters and t in seconds) gives the block's position as a function of time?
x = 6 sin(10t + 0.5π)
x = 6 sin(10πt + 0.5π)
x = 6 sin(10πt - 0.5π)
x = 6 sin(10t)
x = 6 sin(10t - 0.5π)
