Enter the distance traveled (m) and the initial velocity (m/s) into the Calculator. The calculator will evaluate the Initial Angle. 

Initial Angle Formula

IA = 1/2*asin(g*d/v^2) *57.2958


  • IA is the Initial Angle (degrees)
  • d is the distance traveled (m)
  • v is the initial velocity (m/s)

How to Calculate Initial Angle?

The following steps outline how to calculate the Initial Angle.

  1. First, determine the distance traveled (m). 
  2. Next, determine the initial velocity (m/s). 
  3. Next, gather the formula from above = IA = 1/2*asin(g*d/v^2) *57.2958.
  4. Finally, calculate the Initial Angle.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

distance traveled (m) = 300

initial velocity (m/s) = 40
