Math:Launch Formula Work

R= ((Vo^2)(sin2)(theta)/(g))

step 1--> 0=((Vo^2)(sin2)(35)/32.2))

step 2--> CROSS MULTIPLY & SIMPLIFY--> ((0=Vo^2)(sin)(70))

step 3--> DIVIDE BY (sin)(70) --> ((0/((sin2)(35))=((Vo^2)/((sin)(70))

step 4--> SIMPLIFY--> 0=Vo^2

step 5--> SQUARE ROOT IT--> 0=Vo

The intial velocity is zero.
