Question

A spring scale exerts a net force of 8.5 N on an object. What is the object's mass if it has an acceleration of

Answer 1

Answer:

mass of the object is 2.18 kg

Explanation:

Given

Force (F) = 8.5 N = 8.5 kg.m/$s^{2}$

acceleration (a) = 3.9 m/$s^{2}$

Mass (m) = ?

We know that the newton's second law of motion gives the relation between mass of ab object. force acted upon and the amount the object is accelerated. It is expressed in the form of an equation:

F = ma

mass, m = F/a

               = $\frac{8.5 kgms^{-2} }{3.9 ms^{-2} }$

               = 2.18 kg
