Answer:

10 m


Step-by-step explanation:

When the ball is tossed and jumps to a certain height, all the kinetic energy is converted to potential energy.

Kinetic energy = potential energy

          196 = mgh

where m, g, and h are mass, acceleration due to gravity and height respectively.

196 = mgh

      = 2 × 9.8 × h

      = 19.6h

h = 196/19.6

  = 10 m
