Let us now consider several two-dimensional situations. A particle of mass m is moving in the positive x-direction at speed v. After a certain constant force is applied to the particle, it moves in the positive y-direction at speed 2v.
If the magnitude of the net force acting on the particle is F, how long does it take the particle to acquire its final velocity, 2v in the positive y-direction?
Express your answer in terms of m, F, and v. If you use a numerical coefficient, use three significant figures.

Geologists get to play with chemistry, physics, and history! and what a history you will meet as youwork your way through the course. starting at the beginning, the textbook provides the scientifically acceptedstart of the and promises that you'll get to explore some of the evidence for that scientific view, later inthe semester. meanwhile, which is more nearly correct of the scientifically accepted view? a) the earth formed when the big bang caused older materials to fall together, about 14 billion years ago.b) the earth formed from the falling together of older materials, about 4.6 billion years ago.c) the earth formed in the big bang, about 6000 years ago.d) the earth is eternal, having been here forever and promising to be here forever.e) the earth was assembled by gigantic space beavers, which gnawed down the primordial tree of life andpiled its branches together to form the planet.
