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
