pls let me know how to do this

6. [I1 Points] LARCALC11 12.3.037.MI. ASK YOUR TEACHER PRACTICE ANOTHER A shot fired from a gun with a muzzle velocity of 1400 feet per second is to hit a target 2800 feet away. Determine the minimum angle of elevation of the gun. (Round your answer to two decimal places.) E Need Help? Use the model for projectile motion, assuming there is no air resistance and g = 32 feet per second per second. 7. [-/1 Points] LARCALC11 123.041. ASK YOUR TEACHER PRACTICE ANOTHER Determine the maximum height and range of a projectile fired at a height of 1.1 meters above the ground with an initial speed of 80 meters per second and at an angle of 30" above the horizontal. (Round your answers to two decimal places) WE\". Need Help? Use the model for projectile motion, assuming there is no air resistance and g = 9.3 meters per second per second. . [/1 Points] DETAILS LARCALC11 12.3.045. Consider the motion of a point (or particle) on the circumference of a rolling circle. As the circle rolls, it generates the cycloid r(t) = b((ut sin wt)i + b(1 cos wt)j where a) is the constant angular speed of the circle and b is the radius of the circle. Find the velocity v(t) and acceleration a(t) vectors of the particle. V\") = a(t) = Use the results to determine the times at which the speed wt of the particle will be zero and maximized when 0
