You are driving your small, fuel-efficient car when you have a head-on collision with a big, fuel-efficient truck that is three times as massive as your car. head-on means, for example that if you are traveling in the positive x direction, the truck is traveling in the negative x direction. right before the collision, you were traveling at a speed of 3.0 m/s and right after the collision, both vehicles are at rest. due to the conservation of the momentum, you can find the speed of the truck before the collision. what was the kinetic energy of the truck ktruck before the collision when the kinetic energy of the car was kcar

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
