On the moon, the acceleration of a free-falling object is −1.6 meters per second per second. a stone is dropped from a cliff on the moon and hits the surface of the moon 16 seconds later. how far did it fall? (round your answer to one decimal place.)

The radius of a sphere is increasing at a rate of 9 cm/ sec. find the radius of the sphere when the volume and the radius of the sphere are increasing at the same numerical rate.

Asmall 12.00g plastic ball is suspended by a string in a uniform, horizontal electric field with a magnitude of 10^3 n/c. if the ball is in equilibrium when the string makes a 30 ° angle with the vertical, what is the net charge on the ball?
