Questions & Step-by-Step Solutions
A 15 kg box is pushed with a force of 45 N. What is the acceleration of the box? (Assume no friction)
Step 1: Identify the mass of the box, which is 15 kg.
Step 2: Identify the force applied to the box, which is 45 N.
Step 3: Recall 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 = 45 N / 15 kg.
Step 5: Calculate the acceleration: 45 N divided by 15 kg equals 3 m/s².
Step 6: Conclude that the acceleration of the box 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.
