A kangaroo has a maximum gravitational potential energy during one jump of 770 J
When the kangaroo lands on the ground 14% of the maximum gravitational potential energy is transferred to elastic potential energy in one tendon.
The tendon has an unstretched length of 35.0 cm
When the kangaroo lands on the ground the tendon stretches to a length of 42.0 cm
Calculate the spring constant of the tendon.

Does the formula for elastic potential energy in an ideal spring get you anywhere.

Is this in the aqa 2019 physis paper 2? If not do you know any topics/questions that appear in the paper. Will be very helpful if you share please.
