B) Using the formula F = ma, find the net force on the object with the given mass and acceleration.
C) The net force on the object with a mass of 8 kg and an acceleration of 5 m/s² is...
D) Explain how to determine the net force on an object with mass and acceleration.

Answer 1

The net force on an object with a mass of 8 kg and an acceleration of 5 m/s² is 40 N, calculated using the formula F = ma, where F is force, m is mass, and a is acceleration. The correct option is a.

Step-by-step explanation:

To calculate the net force on an object when given its mass (m) and acceleration (a), you use Newton's second law of motion, which can be written as F = ma. In this example, the object has a mass of 8 kg and an acceleration of 5 m/s2.

Applying the formula, the net force (F) is calculated as: F = 8 kg × 5 m/s2 = 40 N. This means the net force acting on the object is 40 newtons.

To determine the net force on an object using mass and acceleration, simply multiply the two values. This calculation will give you the force in newtons (N), which is the SI unit for force, and is defined as the force required to accelerate a 1-kg object by 1 m/s2. The correct option is a.
