Hi Professor

My name is Esteban and I need some help.  I do not know much about physics, but this past year i've been trying to solve a head on collision between a 98 Dodge ram 1500 quad cab 4x4 (5251 lbs.) and a Pontiac Grand AM 4 door sedan (3650 lbs.).  The pontiac is heading south and the dodge is heading north.  The speed of the car is unknown and the speed of the truck is 43 mph +-.  No breaks where applied to neither vehicles.  The friction of the road is 0.565.  The car heading south crossed over the centerline at an angle of 14 degrees and when realized they where in the oncoming lane they tried to steer to their right which sent their car out of control and made their tail end slide sideways.  the car is still heading in the same 14 degrees, but now going sideway almost at 90 degrees to the 14 degree direction.  Both truck and car impact on the left front bumpers (driver side).  Both left front tires from each vehicle are locked.  The truck is sent backwards about 19 feet and its final resting position is facing east.  The car is sent east of the impact about 18 feet and about 8 feet north of the impact with the car facing south.  the dimensions of the road are 28 feet from edge of pavement to edge of pavement so 14 feet from centerline to EOP. The slope of the road heading south is S=1.45% south and the entire road slopes to the east at 2.75%. 

What I need to know if this is possible and if it is, at what speed does the car need to be traveling to be able to push back the truck?  Please email me if you need any more information at estruiz@msn.com
