An
object with a mass of 10.0 kg is falling under the effect of
gravity near the earth's surface with negligible air resistance.
There is a force of 55 N pushing it to the left (you can pretend
that this force is due to wind if that helps). What is the
magnitude and direction of the total force felt by the object?
Note: if the magnitude is greater than 140 N then you have done
this problem wrong and you need to review vector addition. What is
the magnitude and direction of the acceleration of the object? What
is the normal force? Give one example of when the normal force
acting on an object and the objects' weight are the same, and
another example of when the two are not the same.
