# Massive Equation dump(part 2)

x=v^{2}sin(2theta)/g(when fired from the ground level)

t=(2H/g)^{1/2}

y _{max}=v^{2}sin^{2}(theta)/(2g)

F_{ab}=F_{ba}

W=change in KE

W=Fdcos(theta)

V_{max}= urg^{1/2}

x=r(theta)

v=r(omega)

a=r(alpha)

T=FRsin(theta)

w_{f}^{2}=w_{o}^{2}+2(alpha)(theta)

a_{total}=(a_{c}^{2}+a_{t}^{2})^{1/2}

KE=.5mv^{2}+.5Iw^{2}

There will be another post on just Gravity and I did read about the LaTeX equation editor but i couldn't get it to work
