-------------------------------------------
a) Which object had more kinetic energy being lifted?

b) Which object had more potential energy when it was lifted to a distance of 10 meters? Show your calculation.

Help!!!

3 answers

Ke = (1/2) m v^2

(1/2)*2*2^2 = 4 Joules
(1/2)*4*3^2 = 18 Joules

B) m g h
2*g*10
4*g*10
which is bigger?

This didnt help at all😪

it should be obvious tho
