Consider the moment when the spring is at its maximum compression. At that moment, the kinetic energy, the gravitational potential energy, and the elastic potential energy are, respectively, a -zero, at a maximum, and at a maximum
b -at a maximum, zero, and zero
c -zero, at a maximum, and zero
d -at a maximum, at a maximum, and zero
e -zero, zero, and at a maximum

option C.

Explanation:

As the spring is fully compressed means that velocity of the object will be zero.

If the  velocity of the object is zero then KE will also be zero.

If Kinetic energy is zero Elastic potential energy will be maximum because energy is conserved in this system.

Gravitational PE will be zero because spring will be at the datum.

So, the correct answer will be equal to zero, maximum, zero.

Hence, the correct answer is option C.

it is easily magnetized.

attach the statements so i can answer : )
