Can you explain how to solve for K?

work is done 1. A 1 kg brick is dropped from a height of 10 m. Determine the Ug, K, and Etotal (total mechanical energy) for each height given. (Note: One way to solve for each K is to find the v at each height using a 1-D Motion equation. Instead, see if you can figure out how to find the K values without first finding the speeds.) 1 kg brick Height (m) Ug (joules) K (joules) Etotal (joules) 10 8 6 4 N
