A missile is fired for maximum range with an initial velocity of 20 m/s. If g = 10 m/s², the range of the missile is :
A projectile is fired from the surface of the earth with a velocity of 5ms¯¹ and angle θ with the horizontal. Another projectile fired from another planet with a velocity of 3ms¯¹at the same angle follows a trajectory which is identical with the trajectory of the projectile fired from the earth.
