Use the value of the launch velocity, vo, from Data Table 1. Sin af45 9.8 Sin 28 0.22 RE 2. What is the % difference between the expected distance R2 and the measured value from Data Table 2? 47 3. Derive equation (4). 4, Show the calculation of the initial velocity, vo, of the projectile from the average of the horizontal launch data. 5. Based on information from the data table 1, show the calculation of the relative uncertainty in the projectile velocity. Does the uncertainty in Ri dominate the uncertainty of this calculation? 48

Answer 1

2usine .2 sin2e horizontal velocity time of flight = ucos0 x Horizontal Range 9 9 Your formula is not correct. This is the correct formula. Your other data and information is missing. Like initial velocity. If you can provide all other information then it will be easy for other steps
