Answer:
10 m
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
