2. Given the equations below and assuming an uncertainty in k of 8k, uncertainty in m of Sm, uncertainty in x of 8x, uncertainty in v of dv, and g is a constant, what are the expressions for the uncertainties in the Spring Potential Energy, Uspring, the Gravi- tational Potential Energy, Ug and the Kinetic Energy, K? Refer to the uncertainty rules described in the Introductory Information chapter of the lab manual. Show your work! Uspring Ug = 1 kx 2 = mgx 1 K = mv 2
