Question

A force of 400 N causes a 80-kg fullback to accelerate. What is the acceleration experienced by the fullback?

a) 2 m/s²
b) 5 m/s²
c) 8 m/s²
d) 10 m/s²

Answer 1

The acceleration experienced by the fullback, using Newton's second law (F = ma), with a force of 400 N and mass of 80 kg, is calculated to be 5 m/s².

Step-by-step explanation:

To find the acceleration experienced by the fullback, we can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma). In this case, we are given a force (F) of 400 N and a mass (m) of 80 kg.

Using the formula, we can solve for acceleration (a) as follows:

a = F / m

a = 400 N / 80 kg

a = 5 m/s²

Therefore, the acceleration experienced by the fullback is 5 m/s², which corresponds to option b).
