In the video, i drop a ball off a three-story balcony. we know that objects in freefall follow the equation for height h, in meters, h = − 4.9 t 2 + c , where t is time in seconds, and c is the initial height. a student timed the drop at 1.3 seconds. use this to determine the height from which the in the video, i drop a ball off a three-story balcony. we know that objects in freefall follow the equation for height h, in meters, h = − 4.9 t 2 + c , where t is time in seconds, and c is the initial height. a student timed the drop at 1.3 seconds. use this to determine the height from which the ball was dropped, to at least 2 decimal places. ball was dropped, to at least 2 decimal places.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
