U are rolling balls along the floor of a tub to try and make them fly out. u roll a 0.5kg ball along the bottem of the tub at 3m/s. the top edge of the tub is 0.5m above the bottem. calculate the energy the ball would need in order to make it over the tub

Tsunamis are fast-moving waves often generated by underwater earthquakes. in the deep ocean their amplitude is barely noticeable, but upon reaching shore they can rise to an astonishing height of a six-story building. one tsunami generated off the aleutian islands in alaska, had a wavelength of 897km and traveled a distance of 3280km in 4.18h. (a) what was the speed (in m/s) of the wave? find the waves (b) frequency and (c) period.
