Question

How do you use errors in mass and velocity to find the errors in starting and ending kinetic energy?

Equation for KE = 1/2mv^2

Error in m = 0.179kg +/- 0.005 kg

Error in velocity starting = -0.0648m/s +/- 0.011 m/s

Error in velocity ending = 0.259m/s +/- 0.020 m/s

Answer 1

Equation for KE = 1/2mv^2

Given Error in m = 0.179kg +/- 0.005 kg

percentage error in mass

%

Error in velocity starting = -0.0648m/s +/- 0.011 m/s

Percentage Error in velocity starting

%

Error in velocity ending = 0.259m/s +/- 0.020 m/s

Percentage error in velocity ending

%

Starting Kinetic energy KE = 1/2mu²

Percentage error in starting kinetic energy

%

Error in starting kinetic energy KE = 0.0003758+/- 0.000138

ending Kinetic energy KE = 1/2mv²

Percentage error in ending kinetic energy

%

Error in ending kinetic energy KE = 0.006003+/- 0.00109 Ans
