Question

Which transformation of energy takes place when a slingshot launches a stone? (PE stands for potential energy.) A. elastic PE to gravitational PE B. elastic PE to kinetic energy C. gravitational PE to elastic PE D. kinetic energy to gravitational PE

Answer 1

Answer:

B. elastic PE to kinetic energy

Explanation:

As we know that when we stretch the slingshot to some distance then the elastic energy is stored into the sling which is given as

$U = \frac{1}{2}kx^2$

here we know that

k = elastic constant of the sling

x = stretch in the sling

now when we release the sling from that position then the shot will move with certain kinetic energy from it and sling comes to its natural length

so here we can say that elastic potential energy of the sling will convert into kinetic energy of the shot here so correct answer will be

B. elastic PE to kinetic energy

Answer 2

B. Elastic potential to kinetic energy

The elastic potential energy in the slingshot will be transferred to the stone as kinetic energy as the stone is launched.
