Un atleta de masa m = 70 kg y altura L = 1.80 m está haciendo flexiones sobre una superficie horizontal sin rozamiento. Su centro de masas se encuentra a una distancia LCM = 1.20 m del punto de apoyo O (ver figura). La distancia entre las manos y el punto B es LAB = 0.2 m. Calcular las reacciones del suelo sobre las manos y los pies del atleta cuando su cuerpo forma un ángulo θ = 20° con la horizontal.

The median of a data set is the measure of center that is found by adding the data values and dividing the total by the number of data values that is the value that occurs with the greatest frequency that is the value midway between the maximum and minimum values in the original data set that is the middle value when the original data values are arranged in order of increasing (or decreasing) magnitude

Four individuals pool money together to start a new business and agree to split the profits equally. n invests $6,000, x invests $2,000, y invests $8,000 and z invests $4,000. if the profits for the first month were $100,000, y receives than if the profits were divided in proportion to how much they invested.
