To understand how to find the velocities of particles after a collision. there are two main types of collisions that you will study: elastic and perfectly inelastic. in an elastic collision, kinetic energy is conserved. in a perfectly inelastic collision, the particles stick together and thus retain the same velocity after the collision. there is actually a range of collision types, with elastic and perfectly inelastic at the extreme ends. these extreme cases are easier to solve than the in-between cases. let two objects of equal mass m collide. object 1 has initial velocity v, directed to the right, and object 2 is initially stationary. part a: if the collision is perfectly elastic, what are the final velocities v1 and v2 of objects 1 and 2? part bnow suppose that the collision is perfectly inelastic. what are the velocities v1 and v2 of the two objects after the collision? part cnow assume that the mass of object 1 is 2m, while the mass of object 2 remains m. if the collision is elastic, what are the final velocities v1 and v2 of objects 1 and 2? part dlet the mass of object 1 be m and the mass of object 2 be 3m. if the collision is perfectly inelastic, what are the velocities of the two objects after the collision?

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants

Asatellite that goes around the earth once every 24 hours iscalled a geosynchronous satellite. if a geosynchronoussatellite is in an equatorial orbit, its position appearsstationary with respect to a ground station, and it is known as ageostationary satellite find the radius rof the orbit of a geosynchronous satellite that circles the earth.(note that ris measured from the center of the earth, not the surface.) you mayuse the following constants: the universal gravitational constant g is 6.67 \times 10^{-11}\; {\rm n \; m^2 / kg^2}. the mass of the earth is 5.98 \times 10^{24}\; {\rm kg}. the radius of the earth is 6.38 \times 10^{6}\; {\rm m}.
