Question

Gravity: The force due to gravity is F=mg where g=9.80 m/s². A. Find the force due to gravity on a 41.63-kg object. B. The force due to gravity on an object is 632 kg•m/s². What is the mass?

Answer 1

A. F=mg
= 41.63kg x 9.8m/s²
= 407.974
= 408N (3 significant figure)
B. F=mg
632N= y x 9.8m/s²
y= 632 ÷ 9.8
y = 64.48
y= 64.5kg (3 significant figure)
