When the egg was at the top of the ramp (before it was let go), it had...
potential energy
kinetic energy
no energy
As the egg was falling, it had...

Your egg & protection device was falling with an speed of 10 m/s. It had a mass of 45kg. It hit the ground with a force of 15N. What was the force of the ground back on the egg & protection device?
5N
10N
15N
30N
A group decided to cover their eggs with a bunch of cardboard rings. Their egg did not crack. Why not?
The total time the object was in contact with the ground increased when they added a material with rings that deform. This caused the peak force to increase.
The total time the object was in contact with the ground decreased when they added a material with rings that deform. This caused the peak force to decrease.
