Final answer:
If the force applied to an object is halved, the acceleration would also be halved from 10 m/s^2 to 5 m/s^2, based on Newton's second law of motion.
Step-by-step explanation:
If a constant force is applied to an object, causing the object to accelerate at 10 m/s2, then if the force is halved, the acceleration would also be halved according to Newton's second law of motion (F = ma), where F is the force applied, m is the mass of the object, and a is the acceleration.The acceleration of an object is directly proportional to the force applied to it. If the force is halved, the acceleration will also be halved. In this case, if the object was initially accelerating at 10 m/s^2, halving the force would result in an acceleration of 5 m/s^2.
Therefore, if the force is halved, the acceleration would be 5 m/s2.
