Question

What is the mass of an object that accelerated at 5 m/s2 with a force of 45 n?

Answer 1

Answer:

9kg.

Explanation:

Data obtained from the question include:

F (force) = 45N

a (acceleration) = 5 m/s2

m (mass) =?

Force is simply the product of mass and acceleration as given by the formula: F = ma. With this formula (i.e F = ma) we can easily calculate the mass of the object. This is illustrated below:

F = ma

m = F/a

m = 45/5

m = 9kg.

Therefore, the mass of the object is 9kg
