A crate, which has a mass of m= 45 kg, is being accelerated at 3.2m/s^-2 up an frictionless inclined plane, which meets the horizontal at an angle of 35 degrees, by a rope.
What is the magnitude of the normal force acting on the crate?
What is the tension acting in the rope?

  • Physics -

    Net force= Tension + normal force + weigh
    I used net force= ma.
    I got Normal force= ma + mgCos(angle)
    Normal force to be 505N.

    Tension= ma + mgSin(angle)
    = 396
    Is this correct? or is the Net force = o.

  • Physics -


    ma=T-mgsinα =>
