If the velocity of a projectile is known at t=1second and the gravitational force is unknown, how does one determine the velocity at t=0, 2, and 3 seconds.(adsbygoogle = window.adsbygoogle || []).push({});

The projectile does not start from rest.

If i use the formula: vfy = viy - gt, i can't solve for v, since the value for g is unknown.

Thank you .
