السلام عليكم ورحمة الله وبركاته
أتمنى منكم حل هذي المسائل لاني م عرفت احلها :confused:
1l a block spring system oscillates with amplitude of 3.50 cm . if the spring constant is 250 N/m and the mass of the block is 0.500 kg , determine (a) the mechanical energy of the system , (b) the maximum speed of the blpck ,and (c) the maximum acceleration
2l a physical pendulum in the form of a planar objwct moves in simple harmonic motion with a frequency of 0.450 Hz . the pendulum has a mass of 2.20 kg and the pivot is located 0.350 m from the center of mass. determine the moment of inertia of the pendulum about the pivot point.
3l A simple pendulum has a mass of 0.250 kg and a length of 1.00 m it is displaced through an angle of 15.0 degree and then released. using the analysis model of a particle in simple harmonic motion find (a) the maximum speed of the bob (b) its maximum angular acceleration and (c) the maximum restoring force on the bob
4l a 1 meter long pendulum has a bob with a mass of 1 kg suppose that the bob is now tied to a different string so that the length of the pendulum is now 2m . how will the period of the pendulum change ?
choose (a) increase (b) decrease (c) same
وششكرا :)
