For a horizontal launch (θ0 = 0) at a fixed height ℎi > 0, are the statements below correct? (Assuming friction can be ignored.) 1. The object is moving along a straight line. 2. The acceleration in the horizontal direction is zero. 3. No matter how fast the object is launched, the travel time is always the same. 4. No matter how fast the object is launched, the horizontal travel distance Δx is always the same.
