Δz/z = Δy/y ?

Okay I did the work right though I just wrote delta V instead of delta v^2? 1/2 is just a constant in the kinetic energy formula. I just treat it as something still being multiplied?

Homework Statement An object of mass m = 2.3 ± 0.1 kg is moving at a speed of v = 1.25 ± 0.03 m/s. Calculate the kinetic energy (K =(1/2)mv2) of the object. What is the uncertainty in K?Homework Equations Δz = |z| ( Δx/x + Δy/y ) - Multiplication Δz = n (xn-1) Δx - Power The Attempt at a...
