As science becomes more sophisticated, researchers develop coherent theories about the workings of matter and energy. These ideas were not always on the right track, despite extensive initial evidence. For example, "the opinion of many scientists was that heat energy and work energy were different types of universal fluids that flowed from object to object as they interacted. They also believed that certain interactions required no exchange of energy at all." While these theories could be explained through evidence available at the time, they were eventually proven wrong by further discoveries. Science is not fact, but rather our attempt to best explain something with the limitations we have with regards to technology, etc.

500= (1.96) (4700/sqrt(n)) This is the answer is n = (1.96)^2 (4700)^2 /(500)^2 =339.44

Why is it that, rather than n = (1.96)^2 (4700)^2 - (500)^2
not sure on the algebra why we divide by 500squared rather than subtracting it.

A wheel of radius 0.20 m is mounted on a frictionless horizontal axis. The rotational inertia of the wheel about the axis is 0.050 kg · m2.A massless cord wrapped around the wheel is attached to a 2.0 kg block that slides on a horizontal frictionless surface. If a horizontal force of magnitude P = 3.0 N is applied to the block as shown in Fig. 11-35, what is the magnitude of the rotational acceleration of the wheel? Assume that the string does not slip on the wheel.

A 49.0 kg person holding two 0.850 kg bricks stands on a 2.10 kg skateboard. Initially, the skateboard and the person are at rest. The person now throws the two bricks at the same time so that their speed relative to the person is 21.8 m/s. What is the recoil speed of the person and the skateboard relative to the ground, assuming the skateboard moves without friction?
