a small dog is trained to jump straight up a distance of 1.2m how much kinetic energy does the 7.2-kg dog need to jump this high (the accerlation due to gravity is 9. 8m/2 show yourk

Question

Feel free to ask if u face any confusion?

shamim · Answer

This potential energy is at 1.2m height

shamim · Answer

Kinetic energy of dog on ground is equal to potential energy at 1.2m height
