but how do i find the actual height of the second hill, like what do i plug in
jim_thompson5910
  • jim_thompson5910
now plug in v = 49 (speed we want) and g = 32 'g' is the acceleration of gravity of Earth at sea level. This is something you either memorize or look up in a table. It turns out that g = 32 ft/s^2. Every second, a falling object's speed gets 32 ft/s faster
