A projectile is fired from ground level at time t=0, atan angle with respect to the horizontal. It has an initialspeed v0. In this problem we are assuming that the ground islevel. Part A Find the timetH it takes the projectile to reach its maximum height.Express tH in terms ofv0,0 and g (themagnitude of the acceleration due togravity). Part B Find tR, the time at which the projectile hits the ground. Part C Find, H themaximum height attained by the projectile. Express themaximum height in terms of v0,g, and 0. Part D Find the total distance R(often called the range)traveled in the x direction; in other words, find wherethe projectile lands. Express the range in termsofv0.g, ande. H y 0 R
