Parabolic motion, calculation of throwing velocity by travel time and travel distance

작성자 Uploader : 야간비행 작성일 Upload Date: 2019-01-30변경일 Update Date: 2019-01-31조회수 View : 266

If an object was thrown at a specific angle from the horizontal line and its horizontal travel distance and time to fall onto the ground is defined as dt (s) and L (m) respectively,  then the throwing velocity can be obtained as follows. 

Horizontal velocity: Vx = L/dt (m/s) 

Since the time to arrive at the peak point is dt/2, 

Vertical velocity: Vy = (dt/2) * g (m/s) 

Therefore, the throwing velocity is :

V = (Vx^2 + Vy^2)^(1/2) = ( (L/dt)^2 + (dt*g/2)^2 )^(1/2)

*** 참고문헌[References] ***
V = ( (L/dt)^2 + (dt*g/2)^2 )^(1/2)
