Final answer:
By using Newton's second law of motion, we can calculate the force (F) acting on an object using the mass (m) of the object and its acceleration (a). In this case, substituting the values provided into the formula gives a force of 2,744 N.
Step-by-step explanation:
Newton's second law of motion states that the force (F) acting on an object is equal to the mass (m) of the object multiplied by its acceleration (a). The formula for calculating force is F = ma. Given the values in the question, we can substitute the known values into the formula to find the force.
Given: a = 39.2 m/s² and m = 70.0 kg
Substituting the values into the formula: F = (70.0 kg) * (39.2 m/s²)
Calculating the value: F = 2,744 N
