Answer:

25J

Explanation:

Given parameters:

Mass of the watermelon  = 2kg

Speed before touching the ground  = 5m/s

Unknown:

Kinetic energy  = ?

Solution:

To solve this problem, we must understand that kinetic energy is the energy possessed by a body in motion.

    K.E  = [tex]\frac{1}{2}[/tex]  m v²

m is the mass

v is the velocity

Now, insert the parameters and solve;

      K.E  =  [tex]\frac{1}{2}[/tex]  x 2  x  5² = 25J
