PLEASE HELP ME Moving water can be used to produce electricity because...

Kinetic energy can be converted into potential energy, but not vice versa.

Energy cannot be converted into other forms of energy.

Most forms of energy can be converted into other forms.

Potential energy can be converted into kinetic energy, but not vice versa.

c) up

hope this

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
