The initial speed of an arrow is 15m/s

WebDec 21, 2024 · To define the time of flight equation, we should split the formulas into two cases: 1. Launching projectile from the ground (initial height = 0). Let's start with an equation of motion: y = V_ {0}\,t\sin (\alpha) - \frac {1} {2}gt^2, y = V 0 tsin(α) − 21gt2, where: V_0 V 0 – Initial velocity; t t – Time since start of flight; WebWhen you have up as positive and you throw an object up its initial velocity is positive and once it leaves your hand the acceleration of the object is only due to gravity and is …
