Answer:

The total energy is 53 Joule

Step-by-step explanation:

Mechanical Energy

The mechanical energy of an object of mass m, speed v, and at a height h is:

$\displaystyle E = m.g.h+(mv^2)/(2)$

The ball has a mass of m=0.5 Kg, a speed v = 4 m/s, and at a height of h=10 m. Thus the total energy is:

$\displaystyle E = 0.5\cdot 9.8\cdot 10+(0.5\cdot 4^2)/(2)$

E = 49 J + 4 J = 53 J

The total energy is 53 Joule
