#7 on my physics assignment please and thanks I forgot how to calculate this

Answer:
F = 294 N
Explanation:
The force or Weight of an object of 30kg, can be calculated as:
F = mg
Where g is the constant of gravity and it is equal to 9.8 m/s² and m is the mass of the object.
So, replacing m = 30 kg, we get:
F = (30 kg)(9.8 m/s²)
F = 294 N
Therefore, the answer is 294N
