A small toy cart equipped with a spring bumper rolls toward a wall with a speed of v. The cart rebounds from the wall, with the same speed v. The sketch below shows the initial velocity vector v⃗ i, final velocity vector v⃗ f, and the initial momentum vector p⃗ i. Using the initial momentum vector as a basis, draw the change in momentum vector Δp⃗ for the cart. You can obtain each vector's length and orientat
