A ball of mass 0.3kg, moving at a velocity of 20m/s is suddenly hit by a force of 5N for a time of 0.03 sec. Find its new velocity of motion

F * t = m * Δv

F * t = m * (v2 - v1) where v2 is the new velocity and v1 is the current velocity

m * (v2 - v1) = (F * t)

Plugging in the values,

0.3kg * v2 - 0.3kg * 20 m/s = 5 * 0.03 s

0.3 * v2 - 6 = 0.15

0.3 * v2 = 0.15 + 6

v2 = 6.15 / 0.3

v2 = 20.5 m/s

The new velocity of motion is 20.5 m/s.

i think if it were me i whould divide 300 dide 15

step-by-step 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.
