1. The problem statement, all variables and given/known data Vi= 26.06 m/s Mass= 0.5 Kg Angle of launch= 45 degrees time of flight= 3.61 sec range= 64m I need to find the force given to the projectile on the cannon during the launch, and due to the formula F=MA, I am missing A, but I have not formula to find the acceleration of launch. 2. Relevant equations Which formula can be used to find the acceleartion of launch, and how to use it, for example calculate it with Vel in y or in x, 3. The attempt at a solution I have tried using Vf=Vi + AT Vf2=Vo2 + 2ax X=Vit + ½at^2 but each one throws different results, im not sure which one is the right to use, any help will b appreaciated.
