Task 3: Final Velocity and its Uncertainty [a] Find the final velocity and its uncertainty for an object in free fall if the object was dropped from a height of 2.45 i 0.04 m. Consider the acceleration due to gravity is 9.81 i 0.05 m/sz. Recall that the nal velocity in term of displacement is given by v} = 1252 + 29y, where vfis the final velocuity, U); is the intial velocity, and g the acceleration due to gravity and y is the displacement. Hint: since the object was dropped, its initial velocity is zero. Use Eq. (1-7) to nd the uncertainty. Clearly show all steps of your work on paper then take a picture of your calculations and paste it into the spreadsheet that you used for Tasks 1
