Questions & Step-by-Step Solutions
A 20 kg cart is pulled with a force of 80 N. What is the acceleration of the cart? (2023)
Step 1: Identify the mass of the cart, which is 20 kg.
Step 2: Identify the force applied to the cart, which is 80 N.
Step 3: Use the formula F = ma, where F is force, m is mass, and a is acceleration.
Step 4: Rearrange the formula to find acceleration: a = F/m.
Step 5: Substitute the values into the formula: a = 80 N / 20 kg.
Step 6: Calculate the acceleration: a = 4 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.
