Questions & Step-by-Step Solutions
A 5 kg object is subjected to a net force of 15 N. What is the object's acceleration?
Correct Answer: 3 m/s²
Step 1: Identify the mass of the object. The mass is given as 5 kg.
Step 2: Identify the net force acting on the object. The net force is given as 15 N.
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 / 5 kg.
Step 5: Calculate the acceleration: 15 N divided by 5 kg equals 3 m/s².
Step 6: Conclude that the object's acceleration is 3 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.
