Answer:
The horizontal range will be ![2.55\times 10^5m](https://tex.z-dn.net/?f=2.55%5Ctimes%2010%5E5m)
Explanation:
We have given initial speed of the shell u = ![1.6\times 10^3m/sec](https://tex.z-dn.net/?f=1.6%5Ctimes%2010%5E3m%2Fsec)
Angle of projection = 51°
Acceleration due to gravity ![g=9.8m/sec^2](https://tex.z-dn.net/?f=g%3D9.8m%2Fsec%5E2)
We have to find maximum range
Horizontal range in projectile motion is given by
![R=\frac{u^2sin2\Theta }{g}=\frac{(1.60\times 10^3)^2sin(2\times 51^{\circ})}{9.81}=2.55\times 10^5m](https://tex.z-dn.net/?f=R%3D%5Cfrac%7Bu%5E2sin2%5CTheta%20%7D%7Bg%7D%3D%5Cfrac%7B%281.60%5Ctimes%2010%5E3%29%5E2sin%282%5Ctimes%2051%5E%7B%5Ccirc%7D%29%7D%7B9.81%7D%3D2.55%5Ctimes%2010%5E5m)
So the horizontal range will be ![2.55\times 10^5m](https://tex.z-dn.net/?f=2.55%5Ctimes%2010%5E5m)
