A student is moving to college and packs a box so full that they can’t lift it. The student realizes they can push the box across the slick floor to get it to the door. The student applies a force of 40N to the 20 kg. Assume there is negligible friction between the box and the floor.
Calculate the magnitude of the box’s acceleration.
Your answer should have one significant figure.

Respuesta :

According to Newton's laws of motion, the acceleration of the box is

proportional to the applied force.

  • The magnitude of the box's acceleration is 2 m/s²

Reasons:

The given parameters are;

Applied force, F = 40 N

Mass of the box, m = 20 kg

Friction on floor surface = Negligible

Solution;

According to Newton's second law of motion, we have;

Force, F = Mass, m × Acceleration, a

Therefore;

[tex]\displaystyle Acceleration, a = \mathbf{\frac{F}{m}}[/tex]

Assuming the force acts in the direction of motion, we have;

[tex]\displaystyle Acceleration \ of \ the \ box, \ a =\frac{40 \, N}{20 \, kg} = \underline{ 2 \, m/s^2}[/tex]
