Step 1
This energy doesn't just disappear; it gets converted into other forms of energy due to the law of conservation of energy. Some of this energy will be converted into kinetic energy as the ball speeds up. However, we are told not to ignore air resistance. Air Show more…

If the potential energy of a ball held 20 m above the ground is 30 J, what is the total energy of the ball (PE + KE) after it has been dropped and is 5 m from impact?

How much Potential energy is gained by a ball of mass 0.2 kg thrown vertically upwards when it reaches its half rhe height of its highest point if its initial velocity was 30 m/s ?

A ball of mass $1.84 \mathrm{~kg}$ is dropped from a height $y_{1}=1.49 \mathrm{~m}$ and then bounces back up to a height of $y_{2}=0.87 \mathrm{~m}$. How much mechanical energy is lost in the bounce? The effect of air resistance has been experimentally found to be negligible in this case, and you can ignore it.
