Find (a) the impulseof the force, (b) the finalvelocity of the object if it isinitially at rest, and (c) thefinal velocity of the objectif it is initially moving alongthe x - axis with a velocity of-2.0 m/s.Most of us know intuitively that in a head-on collisionbetween a large dump truck and a subcompact car, you arebetter off being in the truck than in the car. Why is this? Manypeople imagine that the collision force exerted on the car ismuch greater than that exerted on the truck. To substantiatethis view, they point out that the car is crushed, whereas thetruck is only dented. This idea of unequal forces, of course,is false; Newton’s third law tells us that both objects are actedupon by forces of the same magnitude. The truck suffersless damage because it is made of stronger metal. But whatabout the two drivers? Do they experience the same forces?To answer this question, suppose that each vehicle is initiallymoving at 8.00 m/s and that they undergo a perfectly inelastichead-on collision. Each driver has mass 80.0 kg. Includingthe masses of the drivers, the total masses of the vehicles are800 kg for the car and 4.00 x 103 kg for the truck. If the collisiontime is 0.120 s, what force…
