Ablock of mass 2.40 kg is on a tabletop and is connected to a second block by a pulley. the second block has a mass of 1.80 kg and hangs straight down. when the blocks are released from rest they move through a distance of 0.500 m, at which point the hanging block hits the floor. given that the coefficient of kinetic friction between the first mass and the horizontal tabletop is 0.450, find the speed of the blocks just before the second block lands. (use energy relations to solve.)

the earnings of a typical investor is around $1,000,000 to $10,000,000

hope this !

have a good day!

1   all nations face the problem of scarcity because there are limited resources and unlimited wants. nations do not have enough factors of production to produce everything that their population wants. entrepreneurial resources initiate businesses to make new goods and services; labor resources produce goods and services.

2 there are four factors of production: natural resources, labor resources, capital resources, and entrepreneurial resources. natural resources are raw materials from nature that are used to produce goods. trees, water, and grains are natural resources. some natural resources, such as wheat and cattle, are renewable
