Answer to Question #183919 in Physics for Ahmed Arbed

Question

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 t

o a length of 42.0 cm

Calculate the spring constant of the tendon.
