Impulse is simply the O change in momentum summation of momentum O product of momentum

Airbags are used in cars because they A) Decrease the impulse of a collision B) Decrease the momentum of a collision c) Increase the time of impact of a collision D) Increase the force with which you hit the dashboard O A О в

Your friend says, “When two objects stick together, since they have the same speed, they must have the same momentum after the collision.” Do you agree with your friend? Show why or why not, based on your data.

What is the total impulse within the 12 seconds?

Pls help ASAP.

You hold a beach ball above your head and then throw it upward. Represent the motion of the ball with an impulse-momentum bar chart: (a) For the ball as the system (b) For the ball and Earth as the system

How does momentum and impulse come into play if you were to get kicked in the face by a soccer ball? Please thoroughly explain.

A truck with a mass of 2020 kg and moving with a speed of 17.0 m/s rear-ends a 832 kg car stopped at an intersection. The collision is approximately elastic since the car is in neutral, the brakes are off, the metal bumpers line up well and do not get damaged. (a) Calculate the initial momentum of the truck (in kg m/s).  kg m/s (b) Calculate the final velocities (in m/s) for the truck and the car. vtf= m/svcf= m/s (c) Calculate the total momentum (in kg m/s) of the truck AND the car after the collision.  kg m/s (d) Did you expect the results that you got for Part (a) and (c)?  Yes, since momentum is conserved in a collision with no external forces acting on the colliding objects.No, since there were no forces acting on either the car or the truck during the collision.    No, since kinetic energy may not be conserved.Yes, since the collision is inelastic.

Was momentum conserved in these collisions?  If not, provide a brief explanation.

19. IP A 0.14-kg baseball moves toward home plate with a ve- locity V₁ = (-36 m/s)x. After striking the bat, the ball moves vertically upward with a velocity v = (18 m/s)ŷ. (a) Find the direction and magnitude of the impulse delivered to the ball by the bat. Assume that the ball and bat are in contact for 1.5 ms. (b) How would your answer to part (a) change if the mass of the ball were doubled? (c) How would your answer to part (a) change if the mass of the bat were doubled instead?
