2. Two athletes, red shirt green shirt, play a game of catch. Red shirt stands on the origin "0.0", to begin. Green shirt stands at +5.0 m, or to the right of red shirt. The game begins
with red shirt holding the ball. The ball makes the following motions during the game:
1st pass: 5.0 meters right
2nd pass: 8.0 meters left
3rd pass: 3.0 meters right
4th pass: 6.0 meters left
5th pass: 150 meters right
6th pass: 4.0 meters left

a. Calculate the total displacement of the ball from the origin:
b. Calculate the total distance the ball traveled.
c. Calculate the total distance traveled by the athlete "red shirt" on the left:
d. Calculate the total displacement of the athlete "green shirt" on the right

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
