Questions & Step-by-Step Solutions
A 6 kg object is at rest on a horizontal surface. If a horizontal force of 12 N is applied, what is the acceleration assuming no friction?
Step 1: Identify the mass of the object. The mass is given as 6 kg.
Step 2: Identify the force applied to the object. The force is given as 12 N.
Step 3: Recall the formula for acceleration, which is F = ma, where F is force, m is mass, and a is acceleration.
Step 4: Rearrange the formula to solve for acceleration (a). This gives us a = F/m.
Step 5: Substitute the values into the formula. So, a = 12 N / 6 kg.
Step 6: Perform the division. 12 N divided by 6 kg equals 2 m/s².
Step 7: Conclude that the acceleration of the object is 2 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.
