13. A block is attached to a horizontal spring. On top of this block rests an- other block. The two-block system slides back and forth in simple harmonic motion on a frictionless horizontal surface. At one extreme end of the oscil- lation cycle, where the blocks come to a momentary halt before reversing the direction of their motion, the top block is suddenly lifted vertically upward, without changing the zero velocity of the bottom block. The simple harmonic motion then continues. What happens to the amplitude and the angular fre- quency of the ensuing motion? (a) The amplitude remains the same, and the angular frequency increases. (b) The amplitude increases, and the angular frequency remains the same. (c) Both the amplitude and the angular fre- quency remain the same. (d) Both the amplitude and the angular frequency decrease. (e) Both the amplitude and the angular frequency increase.

Question

13. A block is attached to a horizontal spring. On top of this block rests an-
other block. The two-block system slides back and forth in simple harmonic
motion on a frictionless horizontal surface. At one extreme end of the oscil-
lation cycle, where the blocks come to a momentary halt before reversing the
direction of their motion, the top block is suddenly lifted vertically upward,
without changing the zero velocity of the bottom block. The simple harmonic
motion then continues. What happens to the amplitude and the angular fre-
quency of the ensuing motion? (a) The amplitude remains the same, and the
angular frequency increases. (b) The amplitude increases, and the angular
frequency remains the same. (c) Both the amplitude and the angular fre-
quency remain the same. (d) Both the amplitude and the angular frequency
decrease. (e) Both the amplitude and the angular frequency increase.

A block rests on a frictionless horizontal surface and is attached to a spring. When set into simple harmonic motion, the block oscillates back and forth with an angular frequency of 6.5 rad/s. The drawing shows the position of the block when the spring is unstrained. This position is labeled "x = 0 m." The drawing also shows a small bottle located 0.080 m to the right of this position. The block is pulled to the right, stretching the spring by 0.050 m, and is then thrown to the left. In order for the block to knock over the bottle, it must be thrown with a speed exceeding vo. Ignoring the width of the block, find vo. x=0m الفيسا 0.050 m 0.080 m
Please help me understand this practice problem.
A spring hangs vertically from a ceiling. The spring constant of the spring is k=15 N/m. A 2kg object has been attached to the spring and the spring has already come to its new equilibrium. Someone pulls the object down by 5cm and releases it at time t = 0s. The spring and object begin to oscillate under simple harmonic motion. Find the total energy of the system, the maximum kinetic energy, the maximum potential energy, and the positions where the maximum energies occur. Answers: 0.01875 J, 0.01875 J
An 8.00-kg block is attached to one end of a horizontal spring on a level, frictionless surface. The other end of the spring is attached to a vertical support.
