A 2 kg block slides down a 30 degrees incline as shown above with an acceleration of 2 m/s?
10°
Which of the following correctly indicates the magnitudes of the forces acting up and down the incline?

The magnitude of the force acting up and down the incline is 16.97 N.

The given parameters:

  • mass of the block, m = 2 kg
  • inclination of the plane, θ = 30⁰
  • speed of the block, v = 2 m/s

The magnitude of the force acting up and down the incline is calculated as follows;

[tex]\Sigma F = 0 \\\\N - Wcos(\theta) = 0[/tex]

where;

N is the normal reaction, acting upwards

W is the weight of the block, acting downwards

[tex]N = W cos (\theta)\\\\N = mg \ cos(\theta)\\\\N = 2 \times 9.8 \times cos(30)\\\\N = 16.97 \ N[/tex]

Thus, the magnitude of the force acting up and down the incline is 16.97 N.
