A strange science-fiction battle takes on a tiny moon in deep space; here, the moon is so smallthat we can completely ignore gravity. A deranged invading space monster of given mass 28.2kg kicks off a rocky structure to achieve a horizontal speed of 3.45 m/s directly toward a startledspace cadet. The cadet is braced firmly on the surface of the moon and is armed with a rapid-fireautomatic marshmallow blaster gun which fires multiple sticky marshmallows toward the monster, each of mass 11.5 grams and each with a speed of 53.4 m/s. The cadet attempts to stop the monster with the marshmallow gun, slowing the monster down by hitting the monster with marshmallow after marshmallow until the monster is finally brought to a stop. Required:
How many marshmallows will the cadet have to fire at the monster to stop the monster's horizontal motion?

explanation:

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
