Answer
As the speed of the kangaroo increases, the maximum length that the tendon can stretch also increases. This greater extension allows the tendons to store more elastic potential energy.
Step 2
so the elastic potential energy increases

Answer
This increase in stored energy in the tendons translates to a higher amount of elastic potential energy, which contributes to the kangaroo's ability to jump higher.
Step 3
which is transferred to gravitational potential energy

Answer
The elastic potential energy stored in the tendons is converted into gravitational potential energy when the kangaroo jumps, allowing it to achieve greater height.
