An artillery shell is fired so as to land in one piece at x=1000m. Instead it explodes at the top of its parabolic trajectory into two pieces of equal mass. The first piece lands at x=750 m . The other piece happens to hit the ground at the same instant. it lands at x=

Options

A. 1250 m
B. 1750 m
C. `-750 m `
D. 1000m

Answer

1

Explanation

Range =1000
`X_(cm)=(M_(1)x_(1)+M_(2)x_(2))/(M_(1)+M_(2))`
`1000=(M/2(750)+M/2(n))/M`
2(1000-375)=x
1250=x
