Its final kinetic energy (as it leaves the roof) is (Eq. 11-5) . Here we use v to denote the speed of its center of mass and is its angular speed — at the moment it leaves the roof. Since (up to that moment) the ball rolls without sliding we can set v = R = v where R = 0.10 m. Using (Table 10-2(c)), conservation of energy leads to . The mass M cancels from the equation, and we obtain (b) Now ...

Orbital Quantum Number – magnitude of angular momentum . differential equation for radial part R(r) of wave function . it is only about the radial aspect of the electron’s “motion”, of motion towards or away from the proton . E = total energy is in the equation, so it must consist of three parts, radial kinetic energy (although it is not “moving” racially), orbital kinetic energy ...

As the car returns to cruising speed, this energy is transferred back into the translational kinetic energy of the car. The 100-kg flywheel is a hollow cylinder with an inner radius R1 of 25.0 cm, an outer radius R2 of 40.0 cm, and a maximum angular speed of 30,000 rev/min. On a dark and dreary night, the car runs out of gas 15.0 mi from home with the flywheel spinning at maximum speed. Is ...

The total kinetic energy of either the disk or the hoop at the bottom of the ramp will be KEtotal = Mgh, where M is the mass of the body in question and h is the vertical drop of the ramp. The translational kinetic energy of this body will then be KEt = f KEtotal = fMgh, where f is the fraction discussed in …

– Set PE = KErot to solve for the angular speed, (, how fast the arm is rotating in radians per second. Step 4 – Calculate the speed (v) of the ball at release using (and the distance from the ball to the axis. Step 5 – Calculate the range of your projectile using the range equation. Catapults – Since catapults use elastic potential energy, you will use the following equation: PEe = ½ ...
