Suppose you are an astronaut in deep space, far from any source of gravity. You have two objects that look identical, but one has a large mass and the other a small mass. How can you tell the difference between the two?
I.
A 10.0 kg mass is acted on by the two forces:
F = (3.0N)î + (2.0N)j and F, = (10.0N)i + (-7.0N)
a) Express the summation of these two forces in unit vector notation. That is:
%3D
%3!
F=F F+F,
b) What is the acceleration of this mass while these forces are acting? Write your answer in unit
vector notation form.
c) What is the direction of the acceleration (give the angle of acceleration with the x axis) and its
magnetitude?

- Jupiter is about 300 times more massive than Earth. One might quickly conclude that an object on the surface of Jupiter would weigh 300 times more than on the surface of the Earth. For instance, one might expect a person who weighs 500 N on Earth would weigh 150000 N on the surface of Jupiter. Yet this is not the case. In fact, a 500-N person on Earth weighs about 1500 N on the surface of Jupiter.
