Solve the below:
Q: A rail gun fuires a tungtsen projectile horizontally with an exit muzzle velocity of 1500 m/s.The horizontal acceleration of projectile is given as ax=-40vx2+125000vx-96900000 where vx=horizontal velocity.The muzzle is 50m off the ground.At that distance in meters.form the muzzle will be projectile strike the ground if the ground reamains level?Do not neglect the feects due to gravity
