Practice Problems 3 1 . The tensions of the ropes acting on a 1.84 kg object are shown. Find the value of a x , the x -component of the acceleration, if T 1 =9.07 N, T 2 =2.29 N, T 3 =2.15 N, T 4 =3.50 N, and θ=19.3°? Answer: 3.13e+00 m/s^2 -3.13e+00 m/s^2 2 . Find the value of a y , the y -component of the acceleration. Answer: -5.51e-01 m/s^2 5.51e-01 m/s^2 3 . The tensions of the ropes acting on a 3.10 kg object are shown. Find the value of a x , the x -component of the acceleration, if T 1 =3.90 N, T 2 =2.20 N, T 3 =4.70 N, T 4 =4.00 N, and θ=12.0°? Answer: 1.73e-02 m/s^2 -1.73e-02 m/s^2 4 .
