Imagine a spinning solid melon. It has a mass of 1.0 kg and a 18-cm diameter. It turns a rate of 77rev/min. Find its kinetic Energy If an additional 5.0mJ of energy are added to the rotational energy, what is the new angular velocity of the melon?

When the Sun runs out of nuclear fuel it will collapse into a white dwarf. The present radius of the Sun is R, and the mass is M,. The angular velocity of the Sun is wo. After the Sun collapses into a white dwarf, the radius is R/108. What is the rotational energy of the Sun after it collapses? Assume the Sun loses no mass. - MRw? 5(108") MRw? 5(108) - MRw? 5(1082) O 1084 - MRw? 108 108° - M Rw? 5

I need some help solving this problem: The angular speed of a point on a planet is 5π/11 radian per hour. The equator lies on a circle of radius approximately 6000 miles. Find the linear​ velocity, in miles per​ hour, of a point on the equator. Round to the nearest whole number as needed. Thanks so much for your help!

Suppose the width of your fist is 6.4 inches and the length of your arm is 32.6 inches. Based on these measurements, what will be the angular width (in degrees) of your fist held at arm’s length?

This question is similar to one given to me on my homework assignment. I do not understand the values given for the radius (given by my instructor) when trying to find the angular velocity of point E. What radius values and or diameter values do I have to use regarding pythagoreans theroem to obtain the needed radius to plug into VE=rw
