Question

An object has a force of 29.43 N acting on it. Its acceleration is 3.5 m/s2. What is the mass of this object?

Answer 1

The mass of the object is 8.41 Kg.

Step-by-step explanation:

Mechanical Force

The second Newton's law states that the net force exerted by an external agent on an object of mass m is:

F = m.a

Where a is the acceleration of the object. The SI unit for the force is the Newton:
`1\ Nw = 1~Kg.m/s^2`

We are given the net force of F=29.43 N acting on an object and producing an acceleration of a=3.5~m/s^2.

To calculate the mass of the object, we solve the above equation for m:

`\displaystyle m=(F)/(a)`

`\displaystyle m=(29.43)/(3.5)`

Calculating:

m = 8.41 Kg

The mass of the object is 8.41 Kg.
