The correct option is c that is change in momentum
hence Impulse= change in momentum.

Learning Goal: To understand the relationship between force, impulse, and momentum. The effect of a net force ΣF⃗ acting on an object is related both to the force and to the total time the force acts on the object. The physical quantity impulse J⃗ is a measure of both these effects. For a constant net force, the impulse is given by J⃗ =F⃗ Δt. The impulse is a vector pointing in the same direction as the force vector. The units...

Question 1 4 pts In a collision, an object experience a force for a specific amount of time that results in a change in the object momentum. The product of this force (F) and the time (t) for which the force acts is the Impulse (1) of the force. The SI unit of MOMENTUM and IMPULSE are: O Kgm/s and Ns respectively ONone of the above OKg and N respectively O Ns and kgm/s Question 2 3 pts It is...
An impulse is a change in momentum usually over a short time. For which of the following is the force the greatest on a stress test automobile is remotely driven at 50 mph? A. Car hits and sticks to a stationary vehicle B. Car bounces off a wall C. Car hits a sand pile D. Car lands in the lake
Impulse is defined as the change in momentum of an object in a collision. Impulse = mass * δv = mass * (vfinal - vinitial). Given these values: mass = 0.2986 [kg] and velocityinitial = 0.383 [ms-1] and velocityfinal = -0.3064 [ms-1], what is the Impulse? Use three significant figures and answer in Ns. Note: 1 [kg ms-1] = 1 [Ns] (Ns = Newton Second) and 1 [Newton] = 1 [kg ms-2]. What does impulse equal?
