Question

Suppose that for the three launches from a given height   h   you get the following data.  (Note:  the numerical values in this table of data are randomized.   

Calculate the average time and distance and the uncertainties in both averages using Eqs. (E.5) and (E.5b) from the Lab 1 manual, Uncertainty, Errors and Graphs.  Be careful to use the appropriate number of significant figures for the precision of the data given in the table.  You must enter the units (using MapleTA syntax) for each quantity; put the respective units in the appropriate "units" box.

If the effective diameter of the ball is  0.014

time  t(s) distance  x(m) 0.0189 0.329 0.0184 0.321 0.0189 0.326 In Lab 3 you will do each launch from a given height h above the floor three times and, therefore, measure three values of the time it takes for the (effective diameter of the) ball to pass through the photogate and the three corresponding values of the horizontal distance the ball travels from the launch until it strikes the floor. Suppose that for the three launches from a given height h you get the following data. (Note: the numerical values in this table of data are randomized.

Be careful to use the appropriate number of significant figures for the precision of the data given in the table. You must enter the units (using MapleTA syntax) for each quantity; put the respective units in the appropriate "units" box. If the effective diameter of the ball is 0.014 plusminus 0.001 m , what is the horizontal velocity Vx of the ball and its absolute uncertainty DeltaVx ? (Hint: You need to use Eq. (E.7) from the Lab 1 manual for the absolute uncertainty). Vx = DeltaVx =
