SUMMARY
The force required to accelerate a 2.0 kg ball at 3.0 m/s² is calculated using Newton's second law, F=ma. For a frictionless horizontal surface, the force is 6 N. In the case of vertical acceleration, the force must also account for the weight of the object, calculated using w=mg, where g is the acceleration due to gravity (approximately 9.81 m/s²). Therefore, the total force for vertical acceleration is the sum of the force needed to overcome gravity and the force for acceleration.
