Ablock with mass m1 of 2.85 kg moves along an inclined plane that makes an angle of 40.0 degrees with the horizontal, and is connected by a string that passes over a pulley to a second block that has a mass m2 of 4.75 kg. both blocks are composed of the same material. the string and pulley have negligible mass and the pulley exerts no friction force on the string. the coefficient of kinetic friction between the plane and the block is 0.55. determine the magnitude and direction of the acceleration.

The freezing and boiling point of a substance changes as the air pressure around it changes. for example, at a lower air pressure (higher altitude) it is easier for water molecules to escape from liquid into the air. in a high altitude city such as denver, colorado compared to a sea-level city such as houston, texas, water
