Question

A force 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?

Answer 1

F=ma
8480=26.5m
m=8480/26.5
m=320
Mass is 320kg.

Answer 2

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

$F = m * a$

Where:

F: It's the strength

m: It's the mass

a: It's the acceleration

According to the data we have to:

$F = 8,480N\\a = 26.5 \frac {m} {s ^ 2}$

If we clear the mass of the formula we have:

$m = \frac {F} {a}\\m = \frac {8,480} {26.5} = 320kg$

Answer:

The mass of the chart is 320kg
