alright thanks

work is a force acting over a distance. is the force gravity?

P=W/change in time but how do i find the work?

reginald esuke from cameroon ran down a mountain slope from an elevation of 4095m to one of 915m in just 62.25min. if esukes mass was 70.0kg, what was the average power during his descent?

haha alright well thanks for all the help.

so i divide the work done by 5.0m or 10.0m or 15.0m? the back of the book says the answer should be -1500N and i can't get that no matter how i do it

14.0m/s ? 4900J ? wouldnt the change just be -4900J since the KEf would be 0? so work done is the same as change in kinetic energy... what am i doing wrong?

Homework Statement A 50.0 kg diver steps off a 10.0 m high diving board and drops straight down into the water. If the diver comes to rest 5.0 m below the surface of the water, determine the average resistance force exerted on the diver by the water. Homework Equations PEg=mgh KE=1/2...
