    Solving Pulley Problem with Newton's Laws: Calculating Acceleration of Bodies

    It was a typo.It is common sense because the hanging body is held up by two wires so the tension doubles but differently.

    Solving Pulley Problem with Newton's Laws: Calculating Acceleration of Bodies

    Calculating Crate Acceleration: Force, Friction, and Net Force

    Simple method: Force by push - force by friction = mass of block *acceleration. 730-.19*(210*9.8) = 210 * a >338.98= 210 * a >a= 338.98/210= 1.6141 m/s^2
