Question

forces unit 1 test review an object is accelerating at a rate of 4.5 m/s² with a net force of 4,500 n. what is the mass of the object? kg

Explanation:

Step1: Recall Newton's Second Law

Newton's second law is \( F = ma \), where \( F \) is force, \( m \) is mass, and \( a \) is acceleration. We need to solve for \( m \), so rearrange the formula to \( m=\frac{F}{a} \).

Step2: Substitute the given values

We know \( F = 4500\ N \) and \( a = 4.5\ m/s^2 \). Substitute these into the formula: \( m=\frac{4500}{4.5} \).

Step3: Calculate the mass

\( \frac{4500}{4.5}=1000 \).

Answer:

1000
