# Two automobiles of equal mass approach an intersection. One vehicle is traveling with velocity 13.5 m/s toward the east andthe other is traveling north with speed v2 Neither driver sees the other. The vehicles collide in the intersection and stickangle of 65.0° north of east. Determine the initial speed vtogether, leaving parallel skid marks at anof the northward-moving vehicle.m/sThe speed limit for both roads is 35 mi/h and the driver of the northward-moving vehicle claims he was within the speedlimit when the collision occurred. Is he telling the truth?YesNo

Step 1

Given:

Initial velocity of the car moving in east direction = 13.5 m/s

Initial velocity of the car moving in north direction = v2i

Parallel skid marks at an angle = 650 north of east

Let final velocity of the vehicles = vf

Step 2

By the conservation law of momentum

Step 3

on dividing equatio...
