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 mv2) of the object. What is the uncertainty
The Attempt at a Solution
I have figured out that the kinetic energy is 1.8 J, but how do I figure out the level of uncertainty for this question? We do not use derivatives yet.
Can I take the equation for uncertainty of a power and uncertainy of a constant and add them together? :
change in z= k change in x
=1/2 * 0.1kg
change in z= nx ^n-1 * change in x
=2 * 1.25 ^2-1 * 0.03
then add them together to give an uncertainty of + or - 0.125?
