Faster and higher I believe.
Answer:(10.69, 11.436)
Explanation:
Given
initial height of ball is 2 m
height of basket is 3.05 m
Launching angle![=40^{\circ}](https://tex.z-dn.net/?f=%3D40%5E%7B%5Ccirc%7D)
![x =12\pm 0.27](https://tex.z-dn.net/?f=x%20%3D12%5Cpm%200.27)
y=1.05
equation of trajectory of ball is given by
![y=xtan\theta -\frac{gx^2}{2u^2cos^2\theta }](https://tex.z-dn.net/?f=y%3Dxtan%5Ctheta%20-%5Cfrac%7Bgx%5E2%7D%7B2u%5E2cos%5E2%5Ctheta%20%7D)
for x=12.27
![1.05=12.27\times tan40-\frac{g12.27^2}{2u^2cos^{2}40 }](https://tex.z-dn.net/?f=1.05%3D12.27%5Ctimes%20tan40-%5Cfrac%7Bg12.27%5E2%7D%7B2u%5E2cos%5E%7B2%7D40%20%7D)
u=10.69
for x=11.73
![1.05=11.73\times tan40-\frac{g11.73^2}{2u^2cos^{2}40 }](https://tex.z-dn.net/?f=1.05%3D11.73%5Ctimes%20tan40-%5Cfrac%7Bg11.73%5E2%7D%7B2u%5E2cos%5E%7B2%7D40%20%7D)
u=11.436 m/s
Thus range of speed is (10.69, 11.436)
