Aforce of 8,480 n is applied to a chart to accelerate it at a rate of 26.5 m/s2. what is the mass of the cart?

For this case we have that by definition, Newton's Second Law states that:

Where:

F: It's the strength

m: It's the mass

a: It's the acceleration

According to the data we have to:

If we clear the mass of the formula we have:

The mass of the chart is 320kg
