The final kinetic energy is 1300 J
Explanation:
According to the law of conservation of energy, the total mechanical energy (potential+kinetic) of the bike must be conserved at any point of the motion.
Therefore, we can write:
where:
is the initial kinetic energy of the bike, at the top
is the initial potential energy, at the top
is the final kinetic energy
is the final potential energy
Solving for , we find the final kinetic energy:
