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

During the apollo moon missions, astronauts were concerned about the effects of newton's third law of motion when: o a. they ejected waste water, because they were concerned that it would push them off course. o b. they reentered earth's atmosphere, because they were carrying heavy moon rocks. o c. they took off from earth, because a large force was required to generate large acceleration. o d. they detected incoming space debris, because the inertia of the debris could damage their ship.
