A player hits a baseball with mass of 0.86 kg over the outfield fence. The ball leaves the bat with a speed of 36.0 m/s and a fan in the bleachers catches it 7.2 m above the point where it was hit. Calculate the Kinetic Energy

How does the amount of energy required to hold each proton and neutron in the nucleus compare to the energy released when they are removed?

Which statement correctly describes a step-up transformer? a. it increases the amount of electric energy available. b. it increases the voltage of an electric current. c. it changes direct current into alternating current. d. it has more loops of wire in its primary coil.

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the
