The pulley in the figure has radius R = 1.0m and moment of inertia I = 10kg.m2. The block of mass m = 100 kg is displaced down a distance h from its equilibrium position, and is released from rest at t = 0. Determine the period of oscillation of the pulley. Consider that (k = 1000 N / m)
Engineers are designing a system by which a falling mass m imparts kinetic energy to a rotating uniform drum to which it is attached by thin, very light wire wrapped around the rim of the drum (the figure (Figure 1)). There is no appreciable friction in the axle of the drum, and everything starts from rest. This system is being tested on earth, but it is to be used on Mars, where the acceleration due to gravity is 3.71 m/s2. In the earth tests, when m is set to 13.0 kg and allowed to fall through 5.00 m, it gives 300.0 J of kinetic energy to the drum. If the system is operated on Mars, through what distance would the 13.0-kg mass have to fall to give the same amount of kinetic energy to the drum? How fast would the 13.0-kg mass be moving on Mars just as the drum gained 300.0 J of kinetic energy?

Can you please explain how to find the angle of theta in this problem? The answer states that it is 88.8 degrees but does not explain how. A propeller blade at rest starts to rotate from t = 0 s to t = 5.0 s with a tangential acceleration of the tip of the blade at 3.00m/s^2. The tip of the blade is 1.5 m from the axis of rotation. At t = 5.0 s, what is the total acceleration of the tip of the blade?

The smooth hollow tube assembly rotates about a vertical axis with angular velocity ω=θ˙=3.8ω⁢=θ˙=3.8 rad/s and ω˙=θ¨=−2.4ω˙=θ¨=-2.4 rad/s2. A small 0.23-kg slider P moves inside the horizontal tube portion under the control of the string which passes out the bottom of the assembly. If r=0.88r=0.88 m, r˙=−1.9r˙=-1.9 m/s, and r¨=3.8r¨=3.8 m/s2, determine the tension T in the string and the horizontal force Fθ exerted on the slider by the tube.
