Step 1

We know that the rate of change of momentum is given by the formula: \[\Delta p/\Delta t = m*a\] where m is the mass of the body, a is the acceleration and $\Delta p/\Delta t$ is the rate of change of momentum. Substituting the given values, we get: \[\Delta Show more…

Key Concepts

Newton's Second Law

Newton's second law of motion states that the net force acting on an object is equal to the rate of change of its momentum. This principle, expressed as F = dp/dt, underpins the relationship between the applied force, mass, acceleration, and momentum, and is fundamental in analyzing how forces affect motion.

Momentum

Momentum is a measure of the quantity of motion that an object possesses, calculated as the product of its mass and velocity. Understanding momentum is crucial because it illustrates how mass and velocity contribute to an object's inertial properties and its response to external forces.

Force

Force is an external influence that causes an object to accelerate, changing its state of motion. In mechanics, force is quantitatively linked to the change in momentum of an object and is commonly measured in newtons, emphasizing its role in governing how objects move.
