Hi, I am 12 years old and sort of a noob to physics due to, well, me being in the 8th grade. I need to find the weight of this spherical projectile given just about every other factor, I know the Angle in which it was fired (32.2°), the gravity of the planet this takes place on (12m/s2), the drag (0.2/s), the fire power (16.656 m/s), traveling at 14 1/6 m/s, the distance it goes (51 meters on perfectly flat, level ground), and terminal velocity of 60m/s. The equation needed to find this is really what I need (along with which variable is which), but if you happen to want to take me through the steps, I would appreciate it. I still need the answer if it turns out negative! Thank you for your help.
