Questions & Step-by-Step Solutions
A 15 kg object is pushed with a force of 45 N. What is the acceleration of the object?
Correct Answer: 3 m/s²
Step 1: Identify the mass of the object, which is 15 kg.
Step 2: Identify the force applied to the object, which is 45 N.
Step 3: Use the formula F = ma, where F is force, m is mass, and a is acceleration.
Step 4: Rearrange the formula to find acceleration: a = F/m.
Step 5: Substitute the values into the formula: a = 45 N / 15 kg.
Step 6: Calculate the acceleration: 45 divided by 15 equals 3.
Step 7: Conclude that the acceleration of the object 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.
