If a brick exerts a force of 25 n over an area of 7.34 meters squared how much pressure is the rock putting on the ground? answers

3.4 Pascals Pressure is defined as force per area and we've been given a force of 25 Newtons and an area of 7.34 square meters. So we just need to do the division and make sure we manage the units properly to get the proper unit for the desired measurement. So: 25 N / 7.34 m^2 = 3.40599455 N/m^2 = 3.40599455 kg*m/s^2 / m^2 = 3.40599455 kg/(m*s^2) = 3.40599455 Pascals Rounding to 2 significant figures gives us a pressure of 3.4 Pascals

Answer: fn = wcos50 = 38.89(9.81)(cos50) = 245.23 n
