Final answer:
The force needed to give an object of 35.0kg a 18.0 m/s² acceleration is calculated using Newton's second law, F = ma, resulting in a force of 630 N.
Step-by-step explanation:
The force required to accelerate an object can be calculated using Newton's second law of motion, which is represented by the equation F = ma, where F is the force, m is the mass of the object, and a is the acceleration. In your case, to find the force needed to give an object with a mass of 35.0kg an acceleration of 18.0 m/s², you simply multiply the mass by the acceleration. So, F = 35.0 kg × 18.0 m/s².
Thus, F = 630 N (newtons).
