The horizontal motion of a horizontally launched projectile affects its vertical motion. (FALSE)

A missile launches at a velocity of 30.0 m/s at an angle of 30.0* to the normal. What is the maximum height the missile attains? (11.5 m, I'm not very sure)

In calculating the force of gravity between two objects, if the distance between the objects is increased 4 times, the force of gravity will (DECREASE BY 1/16)

Actually, it will be decreased TO 1/16 of the original force. The way you stated it, the force would be decreased BY 1/16, making it 15/16 of the original force.
