A14-kg dog jumps up in the air to catch a ball. the dog's center of mass is normally 0.20 m above the ground, and he is 0.50 m long. the lowest he can get his center of mass is 0.10 m above the ground, and the highest he can get it before he can no longer push against the ground is 0.60 m .if the maximum force the dog can exert on the ground in pushing off is 2.1 times the gravitational force earth exerts on him, how high can he jump?
