A hockey player has an acceleration of - 3.1m/s. how long does it take him to come to a complete stop from a speed if 13m/s

Two sinusoidal waves, which are identical except for a phase shift, travel along in the same direction. The wave equation of the resultant wave is yR (x, t) = 0.70 m sin⎛ ⎝3.00 m-1 x - 6.28 s-1 t + π/16 rad⎞ ⎠.

When a force on an object increases how does the object's acceleration change?

5) An electron gun sends out a beam of electrons whose kinetic energies are all about 57 μμeV. (1 μeV=1.6*10-25 J1 μeV=1.6*10-25 J.
