a 0.5 kg ball is thrown upward with an iniatial speed of 10 m/s, what is the initial kinetic energy of the ball and the total mechanical energy assuming initial potential energy is zero.

Answer 1

K.E. = (1/2) mv ²
K.E. = (1/2) ( 0.5 kg )( 10 m/s ) ²
K.E. = ______ J

M.E. = K.E. + P.E.
M.E. = ______ J + 0 J
M.E. = ______ J
