Questions & Step-by-Step Solutions
A 15 kg object is subjected to a net force of 45 N. What is its acceleration?
Correct Answer: 3 m/s²
Step 1: Identify the mass of the object, which is 15 kg.
Step 2: Identify the net force acting on the object, which is 45 N.
Step 3: Use the formula for acceleration, which is a = F/m, where F is the force and m is the mass.
Step 4: Substitute the values into the formula: a = 45 N / 15 kg.
Step 5: Calculate the acceleration: 45 N divided by 15 kg equals 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.
