Exercise 102

An astronaut on the Moon fires a projectile from a launcher on a level surface so as to get the maximum range. If the launcher gives the projectile a muzzle velocity of 25 m/s, what is the range of the projectile [ Hint : The acceleration due to gravity on the Moon is only one- sixth of that on the Earth.]
