Answer:
9kg.
Step-by-step 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
