Explanation:
Gravitational potential energy
= mgh
= (2kg)(10N/kg)(5m)
= 100J.
Answer:
Chemical, mechanical, thermal i guess
Answer:
The arrow rise 44.64 m high assuming air friction is negligible
Explanation:
According to the law of conservation of energy
Kinetic energy = Potential energy at highest
----1
We know that F=kx
So,
Substitute the value in 1

Hence the arrow rise 44.64 m high assuming air friction is negligible
Weather
Particles in air such as smoke smog
