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 the acceleration of the block?
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 F = ma, where F is the force, m is the mass, and a is the acceleration.
Step 4: Rearrange the formula to find acceleration: a = F/m.
Step 5: Substitute the values into the formula: a = 30 N / 10 kg.
Step 6: 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.
