Questions & Step-by-Step Solutions
A 10 kg block is at rest on a horizontal surface. If a horizontal force of 30 N is applied, what will be its acceleration?
Step 1: Identify the mass of the block, which is 10 kg.
Step 2: Identify the applied force, which is 30 N.
Step 3: Use the formula for acceleration, which is a = F/m.
Step 4: Substitute the values into the formula: a = 30 N / 10 kg.
Step 5: Calculate the acceleration: a = 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.
