Delta$-$V Problem $-(40\%)$

Let's assume that the drag factor for post impact skid can't be trusted! Instead, on$-$board EDR information is available for vehicle $1$:

Delta$1$x $=+3\mathrm{.}5$ mph $($vehicle x$-$axis$)$

Delta$1$y $=-16\mathrm{.}9$ mph $($vehicle y$-$axis$)$

Determine the following using the EDR data along with the scene information from the above diagram:

$1.$ Magnitude of Delta V vector for vehicle $1$ in mph$.$

$2.$ PDOF for vehicle $1$ in degrees $-$ draw a diagram of vehicle $1$ and show its PDOF.

$3.$ Angle of Delta V vector for vehicle $1$ in global X$,$ Y axes as shown above, using X as reference and CCW being positive $($draw a vector diagram to show your answer$).$

$4.$ Impact speed of Vehicle $1.$
