Newton Second Law of Motion Example Problems with Answers

Newton's 2nd law of motion involves force, mass and acceleration of an object. It is the acceleration of an object produced by an action or force which is directly proportional to the magnitude of the net force in the same direction and inversely proportional to the object mass. Calculate net force, mass and acceleration of an object by referring the below Newton second law of motion example problems with answers.

Newton 2nd Law of Motion Problems with Solutions

Example 1:

Let us consider the problem: A 15 kg object moving to the west with an acceleration of 10m/s2. What is the net force acting on an object?

Solution:

We can calculate Force, Mass and Acceleration using the given formula.

Newton's Second Law of Motion Formulae:

Net Force: Mass: Acceleration: Where, Fnet = Net Force m = Mass a = Acceleration.

Substituting the values in the above given formula,

Net Force (Fnet)= 15 x 10 = 150 N Therefore, the value of Net force = 150 N

Example 2:

Refer the newton 2nd law of motion problems with solutions: A softball has a mass of 1.5 kg and hits the catcher's glove with a force of 30 N? What is the acceleration of the softball?

Solution:

Substituting the values in the above given formula, Acceleration = 30 / 1.5 = 20 m/s2 Therefore, the value of Acceleration is 20 m/s2

Example 3:

Refer the problem with solution: What is the mass of a truck if it produces a force of 15000 N while accelerating at a rate of 6 m/s2?

Solution:

Substituting the values in the above given formula, Mass = 15000 / 6 = 2500 kg Therefore, the value of Mass is 2500 kg
