Two blocks with different mass are attached to either end of a light rope that passes over a light, frictionless pulley that is suspended from the ceiling. The masses are released from rest, and the more massive one starts to descend. After this block has descended a distance 1.40 m , its speed is 3.00 m/s. If the total mass of the two blocks is 18.0 kg, what is the mass of the more massive block? Take free fall acceleration to be 9.80 m/s2.

Move over Jeff Bezos, this invention is about to make you the richest person in the world. You have just invented the OyOy (that's YoYo spelled backwards). It is the very latest in home safety and so easy to use! If your building is on fire, simply reach out and grab the cord on the Oyoy and you will be lowered safely toward the ground at a low velocity. The OyOy has a total mass M = 106.0 kg and is shaped like a cylinder of radius R = 0.835 meters. The secret to the operation of the OyOy is its patented shaft whose radius is only r = 0.0830 meters. The cord is wound around the small shaft and this is the secret to your low velocity. Outer Radius = R Spindle Radius = r Mass = M The FORMULA for the moment of Inertia: I = V(y=0)=? We will use the approximation that the shaft is of negligible mass compared to the total. This means that you can treat the entire OyOy as though it is a solid cylinder with mass M and radius R. Imagine that a customer of mass m = 77.5 kg is using the Oyoy and…
Problem A new type of force was discovered by physicists with the following expression: a Fnew = + Be* + 3x where alpha & beta are constants, and x is the position. The expression above was obtained from the interaction of a massless Higgs Boson (a type of particle) and a black hole, Quantum physicists then decides to design and build a machine that is able to move the Higgs Boson from x2 to x1. How much work should the machine do to achieve this feat? (For simplicity, consider that no energy is lost in the process) Solution To determine the work done we apply the following Xf W = dx Evaluating the above, we get W = e for the limits from xj to xf substituting x1 and x2 as the limits, the work done is expressed as W = | + B X1 ( x15 - x25 ) +
