A small dog is trained to jump straight up a distance of 1.1m. How much kinetic energy…?
September 10th, 2009
does the 7.7-kg dog need to jump this high? (The acceleration due to gravity is 9.8m/s^2.) Show your work.
~ Can someone explain? Do you find the potential energy first?
xo Thanks xo
The KE is equal to the potential energy PE reached
=mgh=7.7×9.8×1.1=83 joules
