Step 1
According to the Newton's first law of motion,
A body continues in its state of rest, or in uniform motion in a straight line, unless acted upon by a force.
Step 2
Assuming I weigh 500 N, I experience a downward gravitational force OAof 500 N.
If am falling down through the air at constant speed, then according to the Newton's first law of motion the net vertical force acting on me is zero. Therefore a force of the air of equal magnitude as the gravitational force (i.e. 500 N) is acting against body in opposite to the gravitational force.
Answer: c) 500 N

A point mass m having charge q is connected with massless spring to a rigid wall on a horizontal surface.A horizontal uniform electric field E is switched on and mass is displaced through a distance x from equilibrium position.
Work done by electric force is W = q E . x as electric force is constant.
But F(external) on spring mas system is equal to kx. So W = k x . x = k x 2 (equation 1) as external force i.e, electric force is constant.
We know that work done is stored in the form of potential energy and we know that potential energy stored in the spring is 1 / 2 k x 2 .
So W = 1 / 2 k x 2 (let it be equation 2)
But the above 2 equations are not equal. From where did the 1/2 come from in the 2nd equation?

We choose a system to be a spring + a connected body. If we stretch the body and leave it, it will make a simple harmonic motion. The center of mass of this system is approximately the center of mass of the body because the spring has a negligible mass. Newton's second law states that: F e x t e r n a l = M a c m However, it is apparent that the center of mass has an acceleration though the total external force on the system is zero. What is the explanation?

A chandelier with mass m is attached to the ceiling of a large concert hall by two cables.Because the ceiling is covered with intricate architectur al decorations (not indicated in the figure, which uses a humbler depiction), the workers who hung the chandelier couldn't attach the cables to the ceiling directly above the chandelier. Instead, they attached the cables to the ceiling near the walls. Cable 1 has tension T1 and makes an angle of θ1 with the ceiling. Cable 2 has tension T2 and makes an angle of θ2 with the ceiling.
Find an expression for T1, the tension in cable 1, that does not depend on T2.
Express your answer in terms of someor all of the variables m,θ1, and θ2, as well as the magnitude of the acceleration due to gravity g.

A box is sliding with a speed of 4.50 m/s on a horizontal surface when, at point P, it encounters a rough section. On the rough section, the coefficient of friction is not constant but starts at .100 at P and increases linerly with distance past P, reaching a value of .600 at 12.5 m past point P. (a) Use the work energy theorem to find how far this box slides before stopping. (b) What is the coefficient of friction at the stopping point? (c) How far would the box have slid iff the friciton coefficient didn't increase, but instead had the constant value of .1?
