SHOW WORK A 3 kg object attached to a spring oscillates with an amplitude of 15 cm and a period of 2s. At a time t=0.5s, the object's position is x=9.1 cm.

Determine...

a) the spring constant of the spring.

b) the total energy of the system (in joules).

c) the maximum speed of the object.

d) the position of the object as a function of time. Use a cosine function.

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
