Questions & Step-by-Step Solutions
A block of mass 5 kg is placed on a frictionless surface. A force of 10 N is applied to it. What is the acceleration of the block?
Step 1: Identify the mass of the block. The mass is given as 5 kg.
Step 2: Identify the force applied to the block. The force is given as 10 N.
Step 3: Recall Newton's second law of motion, which states that Force (F) equals mass (m) times acceleration (a), or F = ma.
Step 4: Rearrange the formula to solve for acceleration (a). This gives us a = F/m.
Step 5: Substitute the values into the formula. We have a = 10 N / 5 kg.
Step 6: Perform the division. 10 N divided by 5 kg equals 2 m/s².
Step 7: Conclude that the acceleration of the block is 2 m/s².
Newton's Second Law – 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.
