If a 0.5 kg ball is thrown up with 250 J of kinetic energy, how high will it go? Assuming no air resistance. (Take g = 10m/s2)
1. At the highest point of the ball's flight, all of its initial kinetic energy will be converted into gravitational potential energy.
2. The formula for gravitational potential energy is:
where:
(mass of the ball),
(acceleration due to gravity),
is the height (which we need to find).
3. At the highest point, the kinetic energy of the ball will be fully converted into potential energy, so:
