Show the calculation of the expected horizontal distance R2 for the incline firing experiment. Use the value of the launch velocity, vo, from Data Table 1. What is the% difference between the expected distance R2 and the measured value from Data Table 2? 2.

Answer 1

Given that Expected horizontal distance = u^2 sin(2 + theta)lg = 7^2 times sin(2 times 30)/9.8 = 4.33 M Phi = difference - (4.33 - 3.9)/3.9 times 100 = 11.02 Here, Range = v cos(theta) times f f = 2 v sin(theta)/g = v^2 sin(2 theta)/g initial velocity v_0 = 3.9 times squareroot 9.87342 = 7 M/sec relative uncertainly = 0.007 times 7 = 0.049 M/sec
