Question

An object weighs 42.53 newtons. What is its mass if a gravitometer indicates that g = 9.83 m/s2?ROUND TO THE NEAREST TENTH.

Answer 1

Answer:

weight =mass× g

42.53=m×9

42.53/98.3

m=4.23

Answer 2

Answer:

m=4.32

Explanation:

according to newtons second law force is directly proportional to accleration when mass acts as constant. This can be expressed as F=ma

Force is denoted as F

mass is denoted as m

acceleration is denoted as a

force is nothing but the weight exerted by the body. so the equation can be expressed as W=ma, where W is weight.

increasing speed because of gravity is given. weight is also given.

m= W/a

m=42.53/9.83

m=4.32
