Questions & Step-by-Step Solutions
A 4 kg block is pulled with a force of 20 N. What is the acceleration of the block? (2020)
Step 1: Identify the mass of the block, which is 4 kg.
Step 2: Identify the force applied to the block, which is 20 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 solve for acceleration (a): a = F/m.
Step 5: Substitute the values into the formula: a = 20 N / 4 kg.
Step 6: Calculate the acceleration: a = 5 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.
