    Meter stick and rock balancing ?

    A uniform meter stick supported at the 25-cm mark is in equilibrium when a 1-kg rock is suspended at the 0-cm end. Is the mass of the meter stick greater than, equal to, or less than the mass of the rock? Explain your reasoning. Thanks in advance for any help!

    How Do Speeds Change After an Elastic Collision?

    Ball A, a 0.055 kg ball, moving with a speed of 2.50 m/s collides head-on with ball B, a 0.095 kg ball initially moving away from it at a speed of 1.15 m/s. Assume a perfectly elastic collision. Take the initial velocity of ball A to be in the positive x direction. (A) What is the speed of...

    Forces and acceleration on frictionless table?

    The two forces F1 and F2 act on a 27.0-kg object on a frictionless tabletop. If F1=10.2 N and F2=16.0 N find the net force on the object and its acceleration for cases (a) and (b). (a) is 90 degrees, in the 3rd quadrant (b) is 120 degrees, from the positive y-axis and moving clockwise To...
