An archer provides 50 J of potential energy to her bow before release the arrow. What will be the kinetic energy of the arrow it is release from the bow?

Kinetic energy of the arrow is 50 J

Explanation:

Here we know that archer stretches the the bow and stores potential energy into the thread

Now when he releases the thread then potential energy of the thread will convert into the kinetic energy of the arrow

This verify the conservation of energy according to which energy neither be created nor be destroyed but it will convert from one form to another form

So here we have

KE = 50 J

need to see circuit to get time constant

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
