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?
Delta X: 201.24 m
Theta (angle): 35.0 degrees
Acceleration (Y): -9.81 meters/seconds/seconds
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?
