1. Two identical blocks A and B are at rest on a horizontal surface with negligible friction. A horizontal force F, is applied on block A for t1 seconds. At the same instant, a horizontal force F2 is applied on block B for t2 seconds. If the two blocks are observed to have the same momentum after the application of the force and if it is known that the magnitude of F2 is twice that of F1, which of the following relationships between t, and tz is TRUE? t2 = 0.5*t1 t2 = 2*t1 t2 = t1 t2 = 1.5*t1

Most of us know intuitively that in a head-on collision between a large dump truck and a subcompact car, you are better off being in the truck than in the car. Why is this? Many people imagine that the collision force exerted on the car is much greater than that exerted on the truck. To substantiate this view, they point out that the car is crushed, whereas the truck is only dented. This idea of unequal forces, of course, is false; Newton's third law tells us that both objects are acted upon by forces of the same magnitude. The truck suffers less damage because it is made of stronger metal. But what about the two drivers? Do they experience the same forces? To answer this question, suppose that each vehicle is initially moving at 7.70 m/s and that they undergo a perfectly inelastic head-on collision. Each driver has mass 72.0 kg. Including the masses of the drivers, the total masses of the vehicles are 800 kg for the car and 4,000 kg for the truck. If the collision time is 0.110 s,…
