Speed amplifier. In Figure block 1 of mass m1 slides along an x axis on a frictionless floor at speed 4.00 m/s. Then it undergoes a one-dimensional elastic collision with stationary block 2 of mass m2 = 2.00m1 Next block 2 undergoes a one-dimensional elastic collision with stationary block 3 of mass m3 = 2.00 m2.

(a) What then is the speed of block 3? Are

(b) The speed,

(c) The kinetic energy, and

(d) The momentum of block 3 greater than, less than, or the same as the initial values for block L?
