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
Answer:
the motion of an object in a circular path , in a fixed orbit
Answer:
Frictional force is produced when two bodies are rubbed against each other. It is the force that oppose the motion and therefore it stops or slow down a moving body.It depends upon the roughness or smoothness of the surface of the body in contact.Rough surface have more friction that the smooth surface. Similarly, the heavier body produces more friction than a lighter body. Frictional force acts in the opposite direction of the motion of the body.
