Need help calculating Task 2 and 3. Along with an explanation of how to complete task 1

Experimental Procedure Task 1: Reproduce plots in Fig 1-2 (a) and [b] (a) Use Excel to reproduce plot in Fig 1-2 [a] and [b]. Be sure to calculate the columns for t3 and 692) not just entered as numbers. (b) On your graphs show the error bars. (c) Use the Trendline tool to fit the data, show the tting equations and the R2 values. (d) Reproduce the results of the LINEST function for the data. Task 2: Density and its Uncertainty To find the density of aluminum, a student used an aluminum cube. She found that its mass is 58.3 i 0.1g and its volume is 21.20 i 0.07cm3. Recall that the density of an object is given by p=M/V, where M is the mass and V is the volume. [a] Find the aluminum density and its uncertainty. Use Eq. [1-7] to find the uncertainty. [b] If the accepted value for aluminum density is 2.71g/cm3. find the percent error in the measured value. 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 Task]. 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} = vi2 + 29y, where vfis the final velocuity, v): is the intial velocity, and g the acceleration due to gravity andy 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
