Homework Statement
I am trying to find the force needed from a spring to launch a mass of 800g to a length of 0.875m. This launch would be at the optimum angle of 45º. I am aware of all projectile motion equations but am having difficulty linking them to force and thus solving the problem itself.
Homework Equations
v^2=u^2+2as, v=u+at, s=ut+1/2at^2
