Applying this formula using the provided data:###
/
~\ast~600~J = 270~J \)So, the maximum kinetic energy of the boy after he bounces is 270 Joules.
Explanation
## Step 1: In this problem, we are given the information that the maximum kinetic energy of the boy after he bounces is 45% of his kinetic energy as he lands. ## Step 2:To calculate the maximum kinetic energy after the bounce, we can apply the percentage to the given kinetic energy as he lands. ### Formula:The formula we use is: ### \(Maximum~kinetic~energy = (Percentage~of~kinetic~energy~after~bounce 💼💼 /\ large💼💼 100)~\ast~ kinetic~energy~as~he~lands \)## Step 3: Substitute the given values into the equation. Let's solve the formula using the provided data such as 45% and 600 J.
