A 2.0 kg mass is tied to a 4.0 kg mass with string B. The 2.0 kg mass is pulled forward with a force of 12 N by string A and both masses accelerate together. Find the acceleration and tension in string B if the surface is frictionless .

Find the acceleration and tension in string B if coefficient of kinetic friction is 0.10

According to the law of conservation of mass, in a chemical reaction the total starting mass of all the reactants equal the total final mass of all the products. true or false?

Acaterpillar tries to climb straight up a wall a meter high, but for every 2 cm up it climbs, it slides down 1 cm. eventually, it reaches the top. when it reaches the top, it does not pull itself over so it will slide down 1 cm. what is the total displacement traveled?
