1200 Joules
Explanation:
To find the dissipated energy during the bounce, we’ll find the difference in potential energy of the ball at the initial height (10 m) and the height after impact (4m).
The formulae for finding Potential energy is;
P.E = m * g * h whereby;
P.E = Potential Energy
M = mass
G = gravity
H = height
(1) Initial P.E
P.E = 20 * 10 * 10
P.E = 2000 Joules
(2) After bounce;
P.E = 20 * 10 * 4
P.E = 800 Joules
(3) The difference (Dissipated Energy);
2000 – 800
= 1200 Joules
