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)

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
