(Projectile Motion) 2.(30 pts) A gun fires a projectile from ground level with an initial velocity vo = 300.0 m/s at a known angle 0 = 35.00 with respect to the horizontal, as shown in Figure 1. Make the usual assumptions for projectile motion and let g = 9.8 m/s' exactly when solving this problem. H H VO ground level Figure 1. Diagram for Problem 2. Determine the two times t, and to when the projectile is at height H of 100.0 m above ground level. Express your answers in units of seconds. Solve the problem algebraically first before substituting values for variables. You'll need to make use of the quadratic formula
