Answer:

4. 2 m/s²

5. Two of the above (both N and kg.m/s² are equivalent)

6. F = m×9.8m/s²

Explanation:

4.

Force = mass × acceleration

40 = 20 × a

a = 40/20

a = 2

5.

Force (in N) = mass (in kg) × acceleration (m/s²)

so the units are equivalent:

N = kg.m/s²

6.

Force = mass × gravity

This is an adaptation of:

Force = mass × acceleration

Gravity is an acceleration of 9.8m/s²
