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 6 2 pts Computation Two objects experience a head-on collision. One object, of mass m2 = 1.85 kg, is moving east at 18.9 m/s, while the other (of mass m2 = 3.93 kg) is moving west at 10.4 m/s. After the collision, the mi object now has a velocity 4.69 m/s to the west. Determine how much kinetic energy was lost during the collision. Note the negative has already been included below. kinetic energy lost = AKE =- Please...

Two cars collide (No external forces) Car 1 has a mass of 2000kg and a velocity of 40 m/s westward. After colliding with the second car (velocity unknown) the 1st car has a velocity of 10 m/s westward. 1st car momentum = 80000 Ns west 1st car velocity change = 30 m/s east. 1st car change in momentum = 60,000 Ns east. If a 1st passenger (m=50kg) is riding the first car, what impulse does the first car apply on...
