Questions & Step-by-Step Solutions
An object is at rest on a frictionless surface. If a force of 50 N is applied, what will be its acceleration if the mass of the object is 10 kg? (2022)
Step 1: Identify the force applied to the object. In this case, the force is 50 N.
Step 2: Identify the mass of the object. Here, the mass is 10 kg.
Step 3: Use the formula for acceleration, which is a = F/m, where 'a' is acceleration, 'F' is force, and 'm' is mass.
Step 4: Substitute the values into the formula: a = 50 N / 10 kg.
Step 5: Calculate the acceleration: 50 N divided by 10 kg equals 5 m/s².
Step 6: Conclude that the acceleration of the object is 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.
Frictionless Surface – Indicates that there are no opposing forces acting on the object, simplifying the calculation of acceleration.
