#### A projectile is fired from the surface of the earth with a velocity of 5ms-1 and angle  with the horizontal. Another projectile fired 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) Option 1) 3.5 Option 2) 5.9 Option 3) 16.3 Option 4) 110.8
