The total momentum of two marbles before collision is 0.6 kg-m/s. No outside forces act on the marbles. What is the total momentum after the collision?

State one advantage and one disadvantage of using a plane mirrior as a driving mirrior

What is the role of the ocular lens?

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.
