Gravitational potential energy is associated with the shape or position of an object.
1.)When an object is placed at height h above ground, gravitational potential energy associated with it is given by,
P.E = mgh
2.)In projectile motion during upward motion, kinetic energy of object is converted into potential energy.
By the help of newtons law of gravitation we can derive keplers third law of planetary motion.
Answer:
2.69 m/s
Explanation:
The equation used is v=(2πr)/T
( (2) (π) (15.0) ) / (35) = 2.69
