1.	A projectile is fired from the surface of the earth with a velocity of 5 ms−1 and angle θ 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 (in ms−2) is(Given g=9.8 ms−2)
Answer» A projectile is fired from the surface of the earth with a velocity of $5 {ms}^{- 1}$ and angle $θ$ 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 (in ${ms}^{- 2}$ ) is (Given $g = 9.8 {ms}^{- 2}$ )
