A projectile is fired from the surface of the earth with a velocity of `5 ms^-1`and angle `theta` with the horizontal. Another projectile fired from another planet with a velocity of `3 ms^-1` at the same angle follows a trajectory which is identical with the trajectory of the projectile fired from the earth. The value of the acceleration due to gravity on the planet is (in `ms^-2`) is: (given `g = 9.8 ms^-2`)
