What is the acceleration of a 15 kg object pushed with a force of 30 N?Select one:a.45 m/s²b.0.5 m/s²c.15 m/s²d.2 m/s²

Break Down the Problem

1. Identify the mass of the object: $m = 15 \, \text{kg}$
2. Identify the applied force: $F = 30 \, \text{N}$
3. Use Newton's second law of motion: $F = m \cdot a$, where $a$ is the acceleration.

Relevant Concepts

• Newton's Second Law states that the acceleration $a$ of an object is directly proportional to the net force $F$ acting on it and inversely proportional to its mass $m$: $a = \frac{F}{m}$

Analysis and Detail

1. Rearranging the formula to calculate acceleration: $a = \frac{F}{m} = \frac{30 \, \text{N}}{15 \, \text{kg}}$
2. Perform the calculation: $a = 2 \, \text{m/s}^2$

Verify and Summarize

• The calculation has been verified. By using Newton’s second law, the acceleration of the 15 kg object pushed with a force of 30 N is indeed 2 m/s².

Final Answer

The correct answer is d. 2 m/s².
