A ball rolls down a hill with a height of 10m and the ball has a mass of 20kg. and then bounces up 4 m and has a gravity of 10. what is it's dissipated energy

Need asap ‼️ 20 pts which gravitational force field diagram is drawn correctly? (answers in pictures below)

How do we measure or think of speed in the united states?

Astone is thrown with a speed v0 and returns to earth, as the drawing shows. ignore friction and air resistance, and consider the initial and final locations of the stone. which one of the following correctly describes the change δpe in the gravitational potential energy and the change δke in the kinetic energy of the stone as it moves from its initial to its final location? options a.δpe = 0 j and δke = 0 j b.δpe is positive and δke is negative c.δpe = 0 j and δke is positive d.δpe is negative and δke is positive e.δpe = 0 j and δke is negative
