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?

The momentum of object 1 is (8.37,5.93) kg m/s. The momentum of object 2 is (3.08,1.87) kg m/s. Object 1 collides with object 2 and they stick together. What is the x-component of the final momentum after the collision if friction is ignored? Assume units of kg m/s and all variables are known to 3 significant figures.

In this activity you will investigate impulse-momentum for a collision. First consider a foam ball colliding with a wall. When will the magnitude of the force on the ball be a maximum? When the hall first starts to compress? While it is compressing? When it has a maximum compression? Explain. Watch the ball collide with a wall several times. Roughly how long does the collision process take? Half a second? Less? Several seconds? Remembering what you observed, attempt a rough...
