Answer:

[tex]\huge\boxed{\sf F = 120\ N}[/tex]

Explanation:

Firstly, we need to find the mass of the skateboard.

Using formula:

F = ma

Where,

  • Force = f = 30 N
  • Acceleration = a = 1.5 m/s²

30 = m (1.5)

Divide 1.5 to both sides

30/1.5 kg = m

20 kg = m

m = 20 kg

Now, finding the force:

Using the same formula.

F = ma

Where,

  • mass = m = 20 kg
  • Acceleration = a = 6 m/s²

F = (20)(6)

F = 120 N
