Answer:

8.85m/s

Explanation:

v=√2gh

v=√2×9.8×4

v=8.85m/s

The watermelon be moving as it strikes the ground below  8.85m/s.

  • Potential energy is the energy possessed by a body because of its position relative to other bodies.
  • Gravitational potential energy is the energy held by a body when it is at some height relative to the zero potential level ground.

The formula that is used to find the velocity in this case is:  

[tex]v=\sqrt{2gh} \\\\v=\sqrt{2*9.8*4}\\\\v=8.85m/s[/tex]

Thus, the velocity will be 8.85 m/s.
