A ball has a M of 7.0 kg, an I of 2.8 x 10^-2 kg-m^2 and a R of 0.10 m. If it rolls down the lane at a linear speed of 4.0 m/s, what is its total kinetic energy?
either:
11J
32J
44J
55J
78J
I keep getting 2 different answer when I either do it myself or i ask the AI but it doesn't clarify why i am wrong or why it is wrong. I am leaning towards 78J but it says 55J
