Questions & Step-by-Step Solutions
A 10 kg object is at rest on a surface. If a force of 30 N is applied, what is the object's acceleration assuming the friction is negligible?
Step 1: Identify the mass of the object. The mass is given as 10 kg.
Step 2: Identify the force applied to the object. The force is given as 30 N.
Step 3: Recall the formula for acceleration, which is a = F/m, where F is the force and m is the mass.
Step 4: Substitute the values into the formula: a = 30 N / 10 kg.
Step 5: Calculate the acceleration: 30 N divided by 10 kg equals 3 m/s².
Step 6: Conclude that the object's acceleration is 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.
Force and Acceleration Relationship – Understanding how to calculate acceleration using the formula a = F/m, where F is the net force and m is the mass.
Negligible Friction Assumption – The problem assumes that friction is negligible, simplifying the calculation of acceleration.
