Step 1: List the known quantities. m = 3.0 kg. u = 0 m s -1 (since it is initially at rest) Step 2: Calculate the impulse. The impulse is the area under the graph. The graph can be split up into two right-angled triangles with a base of 8 s and a height of 4 kN. Area = impulse = 32 × 10 3 Ns. Step 3: Write the equation for impulse.
I want to calculate the impulse that is acting on the car during the first 5.78s. If I know that the force on the car steadily increases from 0 N to 3012 N over this time, determine the impulse. If the mass of the car is 1500 kg, also determine the final velocity of the car. Let’s start by graphing the information we were given.
Define impulse. Describe effects of impulses in everyday life. Determine the average effective force using graphical representation. Calculate average force and impulse given mass, velocity, and time. The effect of a force on an object depends on how long it acts, as well as how great the force is.
OpenStax. Learning Objectives. Explain what an impulse is, physically. Describe what an impulse does. Relate impulses to collisions. Apply the impulse-momentum theorem to solve problems. We have defined momentum to be the product of mass and velocity.
Using the given data about the meteor, and making reasonable guesses about the shape of the meteor and impact time, we first calculate the impulse using Equation 9.6. We then use the relationship between force and impulse Equation 9.5 to estimate the average force during impact.

Δ p = F net Δ t . F net Δ t is known as impulse and this equation is known as the impulse-momentum theorem. From the equation, we see that the impulse equals the average net external force multiplied by the time this force acts. It is equal to the change in momentum.
