Compute the dot product of the vectors u and v, and find the angle between the vectors. Bold v equals 7 Bold i minus Bold j and
Bold w equals negative Bold i plus 7 Bold j Bold v times Bold w = negative 14 (Simplify your answer.) Find the magnitude of the vectors. StartAbsoluteValue Bold v EndAbsoluteValueequals StartRoot 50 EndRoot and StartAbsoluteValue Bold w EndAbsoluteValueequals StartRoot 50 EndRoot (Type exact answers, using radicals as needed.) The angle between the vectors is nothingdegrees. (Type your answer in degrees. Do not round until the final answer. Then round to the nearest tenth as needed.)
Voltage is how fast the electrons flow. Power is a use of voltage times the volumes of electrons. The higher the voltage the more power you have with the same current.
The only thing acting as the roller coaster gets to the bottom is gravity thus acceleration is 9.81
so u use the formula vf^2 = vi^2 + 2abetaD thus distance = vf^2 - vi^2 divided by 2a so 26^2 - 0^2 divided by 2(9.81m/s) equals 676 divided by 2(9.81m/s) = 34.45463812m then use the appropriate 3 sig digs so 34.5m hopes this helps
