A weight lifter lifts a set of weights a vertical distance of 2.00 m. If a constant net force of 350 N is exerted on the weights, what is the work done by the lifter on the weights?

How does an iron nail become a magnet when it is placed in a strong magnetic field

Two objects attract each other with a gravitational force of magnitude 9.20*10^-9 N when separated by 19.2 cm. If the total mass of the objects is 5.01 kg, what is the mass of each?

A 3.0 kg object moving 8.0 m/s in the positive x direction has a one-dimensional elastic collision with an object (mass = M) initially at rest. After the collision the object of unknown mass has a velocity of 6.0 m/s in the positive x direction.
