Be sure and answer both of the questions listed below: Makayla pushes a 200 kg box of books across the floor. The box accelerates at 0.4 m/s2

Question

. Ignoring outside forces, calculate the force on the box. (1 point)
Responses

80 Newtons

.8 m/s^2

500 N

0.002 m/s^2

Answer 1

To calculate the force exerted on the box, you can use Newton's second law of motion, which states:

\[ F = m \times a \]

Where:

• \( F \) is the force,
• \( m \) is the mass of the object,
• \( a \) is the acceleration.

Given:

• The mass \( m = 200 , \text{kg} \)
• The acceleration \( a = 0.4 , \text{m/s}^2 \)

Now, substituting the values into the equation:

\[ F = 200 , \text{kg} \times 0.4 , \text{m/s}^2 = 80 , \text{N} \]

So the force on the box is 80 Newtons.

Therefore, the correct response is: 80 Newtons.
