SOLVE STEP BY STEP IN DIGITAL FORMAT 25.- In the situation of fig. Qf what magnitude is the force of friction of m2, if the tension in the rope that joins them is 0.6 m₁g and m₁ = m₂ = 2 kg? m₂ m₂ 26.- A rifle spring has a force constant of 700N/m, it is compressed 0.051m from its normal length and a bullet weighing 0.134N is placed against the spring in the barrel of the rifle. If there is no friction and the barrel of the rifle is horizontal. With what velocity will the bullet exit the rifle when fired? ИЦУКЕНГШУКЕНГ ШЩЕН ШЩЗХЬ
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.
