How do I calculate final velocity of a planet moving around a star? The things I know are the positions of star/planet initial V of the planet, the masses of the objects. We are also given the time steps or delta t. I have successfully calculated the force, impulse, initial, and final momentum. I am stuck on the Final velocity of the planet after the force of the sun has acted on it. Could someone point me in the right direction? :)
A 51.0-g Super Ball traveling at 27.0 m/s bounces off a brick wall and rebounds at 21.5 m/s. A high-speed camera records this event. If the ball is in contact with the wall for 3.75 ms,
A planar electromagnetic wave is propagating in the +x direction. What is the Poynting vector at the point P at that instant
A uniform plank of length 4.7m and weight 204 N rests horizontally on two supports, with 1.1 m of plank hanging over the right support. To what distance x can a person who weighs 445N walk on the overhanging part of the plank before it just begins ..
Young Jeffrey is bored, and decides to throw some things out of the window for fun. But since he is also very curious, he decides to do so in a controlled way.
One tire is inflated to a pressure of 40 and goes a distance of 18.0 ; the other is at 105 and goes a distance of 93.4. Assume that the net horizontal force is due to rolling friction only and take the free-fall acceleration to be = 9.80.
A 120cm3 box contains helium at a pressure of 2.20atm and a temperature of 80.0â??C. What is the initial thermal energy of each gas?
A penny is placed at the outer edge of a disk radius = .150 m that rotates about an axis that is perpendicular to the plane of the disk at the center. The period of the rotation is 1.80 s. Find out the minimum coefficient of friction neccesary to..
