Question

A wagon has a mass of 100 grams and an acceleration of 2 m/s2. What is the force on this wagon?

Answer 1

0.2 Newtons

Explanation:

Newton's Second Law of Motion states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

Newton's Second Law formula:

F = m * a

Where:

F: the magnitude of the net force, in N

m: the mass of the object, in Kilogram

a: the acceleration of the object, in m/s2

Answer 2

The force on this wagon is 0.2 Netwons.

Explanation:

Givens

`m=100 gr`

`a= 2m/s^(2)`

First, we need to transform the mass to kilograms, we know that 1 kilogram equals 1000 grams.

`100gr(1kg)/(1000gr) =0.1 kg`

Then, by Newton's Second Law, we have

`F=ma`

Replacing each variable

`F=0.1kg(2m/s^(2) )\\F=0.2 N`

Therefore, the force on this wagon is 0.2 Netwons.
