A basketball is thrown at 45° to the horizontal. The hoop is located 4.5m away horizontally at a height of 1m above the point of release. What is the required initial speed?
solve for t in the first equation (in terms of V), put that into the second, and solve for V
how do u solve v?
Put t=4.5/Vcos45 into the second equation, you only have V as the unknown. It is a quadratic, use the quadratic equation.
Not good explanation
