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,
- 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
