14.1-in. spring is compressed to a 8.3-in. length, where it is released from rest and accelerates the sliding block A. The acceleration an initial value of 410 ft/sec² and then decreases linearly with the x-movement of the block, reaching zero when the spring regains original 14.1-in. length. Calculate the time t for the block to go (a) 2.9 in. and (b) 5.8 in. 8.3" -14.1" wwwwww wers: go 2.9 in., t= go 5.8 in., t= i i -0.03728 -0.00021 sec sec
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.
