Explanation / Answer

Here, for the plane ,

let the height is h and range is R

as R/h = 2/1

R = 2h

NOw, R = VA * cos(A) * t

h = VA * cos(A) * t/2

for the trajectory equation

h = R * tan(A) - g * R^2/(2 * (VA * cos(A))^2)

putting values of h and R

VA * cos(A) * t/2 = (VA * cos(A) * t ) * tan(A) - g * (VA * cos(A) * t )^2/(2 * (VA * cos(A))^2)

solving for t

t = VA * (2sin(A) - cos(A))/g

t = VA/g * (2sin(A) - cos(A))

the correct option is 1
