    Elastic collision - Trigonometry equations

    Homework Statement A billiard ball moves at a speed of 4.00m/s and collides elastically with an identical stationary ball. As a result, the stationary ball flies away at a speed of 1.69m/s, as shown in Figure A2.12. Determine: the final speed and direction of the incoming ball after the...

    Problem in the C.G. and torque equilibrium

    I think I get what you suggest. What do you think of this solution. I also added my solution for T1 and I used Newton's law for that.

    Problem in the C.G. and torque equilibrium

    So even though there is more weight (due to the bucket) on one side, the C.G is at the center of the platform?

    Problem in the C.G. and torque equilibrium

    Thank you for your response. I guess I am stuck because I don't know how to calculate the C.G. Do T1 and T2 affect C.G? What about the weight of the platform and its effect on the C.G calculation?

    Problem in the C.G. and torque equilibrium

    Homework Statement A 40.0 kg uniform platform is suspended by two cables, 2.00 m apart, where the centre of the platform lies midway between the cables. A 5.00 kg paint bucket is placed on the platform, 24.0cm to the right of the right cable, as shown in Figure A2.15. What is the tension in...
