Anet force of -1,000 newtons is delivered to the object over a time of .02 seconds. calculate the new velocity of the object.

The change in velocity (v₂ - v₁) is

                 (-20) / (the object's mass).

Call it a crazy hunch, but I can't shake the feeling that there was more
to the question before the part you copied, that mentioned the object's
mass, and its velocity before this force came along.

Magma  is composed of molten rock and is  stored  in the earth's crust. lava is  magma  that reaches the surface of our planet through a volcano vent.
