    (Newton's 2nd & 3rd laws) finding mass

    A mass is hanged by 2 cables, the first makes 30° with the ceiling while the second makes 60° with the ceiling. Find the attached mass if the first tension is 24.5 N and the second tension is 42.7 N. my way: T1=24.5N θ=30 T2=42.7N θ= -60 m=? m=Fnet/a the ans should be (m=5.017 Kg)

    Finding normal force acting on an object (Fn)?

    [b]1. A couch with a mass of 100 kg is placed on an adjustable ramp connected to a truck.If the couch slides down the ramp with an acceleration of 0.8 m/s^2: [b]2. find the normal force on the couch [b]3. my way: Fg=m*9.81=981 Fnety=0N 981 sin 270+f sin 180+Fn sin 90=0N -981Fn=0...
