A ball starts from rest and accelerates at 0.505 m/s2 while moving down an inclined plane 9.10 m long. When it reaches the bottom, the ball rolls up another plane, where, after moving 13.3 m, it comes to rest. What is the speed of the ball at the bottom of the first plane

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
