2014-9: Going Ballistic
The following formula gives the horizontal distance a projectile travels:
Where: v is the initial velocity, θ is the trajectory in degrees, d is the horizontal distance and G is the gravitational constant.
Write a dfn which calculates the distance (in meters) a projectile travels given an initial velocity in meters per second and a trajectory in degrees. Use 9.8 meters per second squared as the gravitational constant.
Examples:
100 (your_function) 45 ⍝ 100 meters per second and 45 degree trajectory
1020.408163
0 (your_function) 45 ⍝ no velocity = no distance
0
100 (your_function) 90 ⍝ shooting straight up = no distance
