Wayne Brian threw a spear a distance of 201.24 meters. Suppose he threw the spear at a 35.0 degree angle with respect to the horizontal. What was the initial speed of the spear?Data Known-

Delta X: 201.24 m

Theta (angle): 35.0 degrees

Acceleration (Y): -9.81 meters/seconds/seconds

Equations-

Velocity(Vx)=Vi(Cosine Theta)

Velocity(Vy)=Vi(Sine Theta)

Time= (Delta X)/Vi(Cosine Theta)

Delta Y= (Vi(Sine Theta)*(Time)) + (1/2(Acceleration Y)*(Time^2))

Delta X= Vi(Cosine Theta)*(2*(Vi*Sine Theta)/(Accelartion Y))

How would you solve the problem when all equations require the intial velocity, and there is none given?
