10 kg
9.8 m/s2
98 N

Correct Answer

(1) 9.8 m/s2
(2) 98 N
(3) 98 N

Explanation

Remember the following

Force equation is

F = ma

and gravity acceleration is 9.8 m/s2

Substitute  as needed to calculate what is missing

  1. It is earth gravity = 9.8 m/s2
  2. Force is F = 10 * 9.8 = 98 N
  3. Weight of the object is the same as force = 98 N
