7. A projectile is fired as seen below. Neglect air resistance, use the given information and \( g= \) \( 9.80 \mathrm{~m} / \mathrm{s}^{2} \). a. Calculate the initial speed of the projectile. Answer: \( 12.0 \mathrm{~m} / \mathrm{s} \) b. Calculate the height the projectile reaches above the \( x \)-axis. c. Calculate the projectile's total time of flight. Answer: \( 3.12 \mathrm{~s} \)
