Box 1 of mass m is on a flat floor and accelerated from rest by a constant net force F over a distance x. The force F ceases to act at the instant block 1 collides with and sticks to box 2, which is initially at rest and made of the same material. The boxes have a total mass M and slide a distance D before coming to rest due to the effects of friction, where the coefficient of kinetic friction is µ. Professor Jovannee Lowfield suggests that the distance D is given by the equation above. Name all aspects of this equation that are implausible.

The man of mass m1 and the woman of mass m2 are standing on opposite ends of the platform of mass m0 which moves with negligible friction and is initially at rest with s = 0. the man and woman begin to approach each other. derive an expression for the displacement s of the platform when the two meet in terms of the displacement x1 of the man relative to the platform.

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.
