    Optimization largest possible volume problem

    Homework Statement A right circular cylinder is inscribed in a cone with height h and base radius r. Find the largest possible volume of such a cylinder. Volume of a cylinder = (pi)(r^2)h Volume of a cone = (1/3)(pi)(r^2)h Homework Equations Volume of a cylinder = (pi)(r^2)h Volume...

    Webpage title: How Fast Does the Shadow of a Dropped Ball Move Along the Ground?

    Related rates problem? If so, you have to come up with a formula that relates the horizontal with the vertical of a triangle. Then differentiate that to come up with an equation that you can solve dx/dt for, which is what you are looking for.

    Particle Motion and Forces: Solving for Velocity, Acceleration, and Force

    Again, you'll want to formulate an equation that gives the position function, and relate that to velocity, then relate that equation to acceleration, at which point you can use Newtons second law to figure out the force acting on the particle.

    The partical of mass 'm' is moving with the laws

    Think about the relationship between position and velocity, and then the relationship between velocity and acceleration.

    Current versus voltage, Very Easy (but stuck)

    Homework Statement The problem gives a graph of Emf versus time, in a circuit consisting of capacitor C and voltage source e. It asks to draw the time dependence of the current I in the circuit. Homework Equations The graph looks like a trapezoid, positive slope starting at Emf=0 t=0...

    Max Power Dissipated in RLC circuit

    Homework Statement For this sample exam, we are given an RLC circuit, with an alternative emf of 1 V, connected all in series with a 500 ohm resistor, a .4 mH inductor, and two capacitors in parallel of 50 pF each. It asks for the "maximum power dissipated by the resistance" and at what...
