Questions & Step-by-Step Solutions
A block of mass 5 kg is resting on a horizontal surface. If a horizontal force of 15 N is applied, what is the acceleration of the block? (Assume no friction) (2021)
Step 1: Identify the mass of the block, which is 5 kg.
Step 2: Identify the applied force, which is 15 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 = 15 N / 5 kg.
Step 5: Calculate the acceleration: 15 N divided by 5 kg equals 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.
