The drawing shows an a-shaped ladder. both sides of the ladder are equal in length. this ladder is standing on a frictionless horizontal surface, and only the crossbar (which has a negligible mass) of the "a" keeps the ladder from collapsing. the ladder is uniform and has a mass of 14.2 kg. determine the tension in the crossbar of the ladder.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
