You need a complete course of study, not just a little help. Really, you should consult with your teacher or a tutor. Simply doing these will show you nothing. You need someone right there explaining things as they go along.

That won't help you. E.G. Science and medicine the kinetic energy of praticle of mass m is found by taking one half of the product of the mass and the square of the velocity V Write an expression for the kinetic energy of a particle. m=1/2 [color=#FF0000] KE = (1/2)mv^2[/color] Compare that with what you have written. As I said, you need a complete course of study/ a teacher/a tutor, not just our written solutions to these problems.
