Consider a shell that has a muzzle velocity of `45ms^(-1)` fired from the tail gun of an airplane moving horizontally with a velocity of `215 ms^(-1)` . The tail gun can be directed at any angle with the vertical in the plane of motion of the airplane. The shell is fired when the plane is above point A on ground, and the plane is above point B on ground when the shell hits the ground. (Assume for simplicity that the Earth is flat)

Options

A. Shell may hit the grond at point `A`
B. Shell may hit the ground at point `B`
C. Shell may hit a point on earth which is behind point `A`
D. Shell may hit a point on earth is ahead of point `B`

Answer

B, D
