Doing a science fair project should i do cafeteria waste or solar power

I think you should do Solar Power that would be so cool to see for a science project

In my opinion solar power is super interesting and many different ways to express the project. Me personally did one and i very much enjoyed it :) please thank and mark brainliest have a great day and good luck

ek = (m·v2) / 2

v - velocity of system after the collision

m = m1 + m2

ek = (m1 + m2) ·v2/2

ek = (200 + 250) ·2,32/2 = 450·5,29/2 = 1190,25 j

the answer was wrong so you should have checked with your pals first
