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.
I keep getting the wrong answer for part c of this problem.
A moving 1.70 kg block collides with a horizontal spring whose spring constant is 303 N/m.
- The block compresses the spring a maximum distance of 14.50 cm from its rest position. The coefficient of kinetic friction between the block and the horizontal surface is 0.120. What is the work done by the spring in bringing the block to rest?
-3.19 J - How much mechanical energy is being dissipated by the
force of friction while the block is being brought to rest by the spring?
2.90×10-1 J - What is the speed of the block when it hits the spring?
1.846 m/s is what I got thats incorrect
