A700-kg car, driving at 29 m/s, hits a brick wall and rebounds with a speed of 4.5 m/s. what is the car’s change in momentum due to this collision? a. 2.3x 10^4 kg·m/s towards the wall b. 2.3x 10^4 kg·m/s away from the wall c. 1.7 x 10^4 kg·m/s away from the wall d. 1.7 x 10^4 kg·m/s towards the wall impulse

C. 1.7 × 10⁴ kg.m/s away from the wall

Explanation:

Change in momentum: This is the product of mass and change in velocity of a body. The Unit of change in momentum is kg.m/s.

Change in momentum of the car = m(v₂ - v₁) Equation 1

Where m = mass of the car, v₁ = initial velocity of the car, v₂ = final velocity of the car.

Given: m = 700 kg, v₁ = 29 m/s, v₂ = 4.5 m/s

Substituting these values into equation 1

Change in momentum of the car = 700(4.5-29)

Change in momentum of the car = 700(-24.5)

Change in momentum of the car = 700(-24.5)

Change in momentum of the car = -17150 kg.m/s

Therefore the Change in momentum of the car is 1.7 × 10⁴ kg.m/s away from the way wall.

The right option is C. 1.7 × 10⁴ kg.m/s away from the wall

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.

prolly a beacuse the momentuem the car has increases while going down hill
