How would i go to solve these?

6. Flight time a projectile launched at an angle is given by: I, = g Explain how you can graphically obtain gravitational field strength g, by plotting If vs. sine. Use this graph to calculate g and compare it with known value of 9.81 m/s?. (Paste the graph with linear fit here.)7. Maximum height of a projectile launched at an angle is given by: H= Vi sinte 2g Explain how you can graphically obtain gravitational field strength g, by plotting H vs. sin'e. Use this graph to calculate g and compare it with known value of 9.81 m/s?. (Paste the graph with linear fit here.) Viz 9 2 tan e2 8. Range of a projectile launched at an angle is given by: R= Vi sin 20 Explain how you can graphically obtain gravitational field strength g, by plotting R vs. sin 20. Use this graph to calculate g and compare it with known value of 9.81 m/s. (Paste the graph with linear fit here.) vi- 9= 2 (tan 0)
