During fireworks display, a shell is shot into the air with an initial speed of |v→0| = 70 m/s at an angle of 75.0∘ above the horizontal, as illustrated on the figure. The fuse is timed to ignite the shell just as it reaches its highest point above the ground. Compute the horizontal v0 x and vertical v0 y components of the initial velocity. (2 points)Using the correct equation compute the maximum height h that the shell will reach. (2 points)Using the correct equation compute the time the shell will take to reach the maximum height h. (2 points)Compute the horizontal displacement Δx. (2 points)
