Explanation:Acceleration is directly proportional to the force and inversely proportional to the mass.(a) If the force is halved, the acceleration will be halved to 3.9 m/s2.(b) If the object's mass is halved, the acceleration will be doubled to 16 m/s2.(c) If the force and the object's mass are both halved, the acceleration will remain the same at 7.8 m/s2.(d) If the force is halved and the object's mass is doubled, the acceleration will be halved to 2.0 m/s2.
