Questions & Step-by-Step Solutions
A force of 15 N is applied to a 3 kg object. What is the resulting acceleration?
Correct Answer: 5 m/s²
Step 1: Identify the force applied to the object. In this case, the force is 15 N (Newtons).
Step 2: Identify the mass of the object. Here, the mass is 3 kg (kilograms).
Step 3: Use the formula for acceleration, which is a = F/m, where 'a' is acceleration, 'F' is force, and 'm' is mass.
Step 4: Substitute the values into the formula: a = 15 N / 3 kg.
Step 5: Calculate the result: 15 divided by 3 equals 5.
Step 6: Write the final answer: The resulting acceleration is 5 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.
