Let two objects of equal mass m collide. object 1 has initial velocity v, directed to the right, and object 2 is initially stationary. a. if the collision is perfectly elastic, what are the final velocities v1 and v2 of objects 1 and 2? give the velocity v1 of object 1 followed by the velocity v2 of object 2, separated by a comma. express each velocity in terms of v. b. now suppose that the collision is perfectly inelastic. what are the velocitiesv1 and v2 of the two objects after the collision? give the velocity v1 of object 1 followed by the velocity v2 of object 2, separated by a comma. express each velocity in terms of v. c. now 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 velocitiesv1 and v2 of objects 1 and 2? give the velocity v1 of object 1 followed by the velocity v2 of object 2, separated by a comma. express each velocity in terms of v. d. let 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? give the velocity v1 of object 1 followed by the velocity v2 of object 2, separated by a comma. express each velocity in terms of v.

Aspring has a natural length of 8 m. if a 12-n force is required to keep it stretched to a length of 10 m, how much work w is required to stretch it from 8 m to 16 m? (round your answer to two decimal places.)

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
