a 1kg ball is thrown into the air with an initial velocity of 30 m/sec. how much kinetic energy does the ball have?

-how much potential energy does the ball have when it reaches the top of its ascent?

-how high into the air did the ball travel?

  • Physics - ,

    Assume potential energy on ground is zero.
    Kinetic energy at 30 m/s
    Potential energy at highest point, H from ground
    Equate energies,
