For the cube from problem 1, instead of having a person push the cube, we are going to attach a spring to it. The box is pulled to compress the spring 50 cm, then released. If the stiffness of the spring is 500 N/m, what acceleration will the cube experience? b. Now, we will move the cube and spring device to a smooth, tile floor, and we will place the cube on wheels. This will lead to some, non-negligible amount of friction. If the coefficient of static friction between the wheels and the floor is 0.07, what acceleration will the cube experience? Replace the single, large cube from the previous problems with two smaller cubes with the masses 5 kg, and 10 kg. Now we're back on the ice. The two cubes are side-by-side. Now a person pushes on box 1 with a force of 50 N at an angle of 30°.
Simple harmonic motion
Simple harmonic motion is a type of periodic motion in which an object undergoes oscillatory motion. The restoring force exerted by the object exhibiting SHM is proportional to the displacement from the equilibrium position. The force is directed towards the mean position. We see many examples of SHM around us, common ones are the motion of a pendulum, spring and vibration of strings in musical instruments, and so on.
Simple Pendulum
A simple pendulum comprises a heavy mass (called bob) attached to one end of the weightless and flexible string.
Oscillation
In Physics, oscillation means a repetitive motion that happens in a variation with respect to time. There is usually a central value, where the object would be at rest. Additionally, there are two or more positions between which the repetitive motion takes place. In mathematics, oscillations can also be described as vibrations. The most common examples of oscillation that is seen in daily lives include the alternating current (AC) or the motion of a moving pendulum.
