Write a functionthat calculates the launch angle, given the target range, altitude and velocity and cannon’s muzzle velocity. function specifications: input arguments: range (r) in meters; altitude (h) in meters; target velocity (v) in m/s; muzzle velocity (vm) in m/s [note: for compatibility with the checker, the arguments must be in this order and the tolerance must be0.001 or better.]output argument: the required launch angle in degrees. use the following test case to validate your function: r = 7,000 m; h = 2,500 m; v = 225m/s; vm = 1,000 m/s= 25.65o2.write a script to apply your function from task 1 to a set of provided target data.
