Question: A 15 kg box is pushed with a force of 30 N. What is the box\'s acceleration?
Options:
1 m/s²
2 m/s²
3 m/s²
4 m/s²
Correct Answer: 3 m/s²
Solution:
Using F = ma, we find acceleration: a = F/m = 30 N / 15 kg = 2 m/s².

Questions & Step-by-Step Solutions
A 15 kg box is pushed with a force of 30 N. What is the box's acceleration?
Step 1: Identify the mass of the box, which is 15 kg.
Step 2: Identify the force applied to the box, which is 30 N.
Step 3: Use the formula for acceleration, which is a = F/m.
Step 4: Substitute the values into the formula: a = 30 N / 15 kg.
Step 5: Calculate the acceleration: a = 2 m/s².
Newton's Second Law of Motion – This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
