Two bodies are falling with negligible air resistance, side by side, above a horizontal plane. if one of the bodies is given an additional horizontal acceleration during its descent, it 1. follows a straight line path along the resultant acceleration vector. 2. has the vertical component of its acceleration altered. 3. has the vertical component of its velocity altered. 4. strikes the plane at the same time as the other body. 5. follows a hyperbolic path.
