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 its acceleration? (Assume no friction)
Step 1: Identify the mass of the block. The mass is given as 10 kg.
Step 2: Identify the force applied to the block. The force is given as 30 N.
Step 3: Recall 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. Here, F = 30 N and m = 10 kg.
Step 5: Calculate the acceleration: a = 30 N / 10 kg.
Step 6: Perform the division: 30 divided by 10 equals 3.
Step 7: Conclude that the acceleration of the block 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.
