A comet of mass m moving with a velocity of +v0 collides inelastically with another comet of mass 4m initially moving with a velocity of -0.5v0. If the comet of mass m has a final velocity of +0.5v0, then determine the final velocity of the other comet in terms of v0. (e. g. the final comet has a velocity of +0.75v0)

F500 j of energy were added to 1 kg of each of these samples, which would experience the least temperature increase?

The focal length of a relaxed human eye is approximately 1.7 cm. when we focus our eyes on a close up object, we can change the refractive power of the eye by about 16 diopters. (a) does the refractive power of our eyes increase or decrease by 16 diopters when we focus closely? explain. (b) calculate the focal length of the eye when we focus closely.
