    Need Help with These AP Physics Problems?

    I need help with some of these problems. Any kind of help will be most appreciated 1. Speed amplifier. In Fig. 10-3, block 1 of mass m1 slides along an x-axis on a frictionless floor with a speed of v1i = 2.80 m/s. Then it undergoes a one-dimensional elastic collision with stationary block 2...
