Show all your calculations. (Rearrange equation 1) Upload an image of your calculations here. Upload Choose a File Question 8 1 pts 5. Calculate the range, use eq. 2 and the launch speed calculated in question #4. Calculate the range when the lancer is aimed at 45°. Show all your work. Upload your file here Upload Choose a File Part II: Calculations When a projectile is launched horizontally its range (R) in meters is given by: 2h R = voy 9 Eq.1 • where the initial height of the launched projectile is above the floor in (m). • g is the acceleration due to gravity. The initial speed of the projectile in m/s. If a projectile is launched at an angle of 45° above the horizontal, its range is given by: loi R II + w? 2hg gV2 V + 29 Eq. 2 Part 2 8.
