Homework Statement
Two vehicles crash at an intersection
Mass of vehicle one: 1858kg
Mass of vehicle two: 2865Kg
Vehicle one was headed North
Vehicle two was headed East
The two vehicles stuck together in a t-bone fashion and the two vehicles left the intersection stuck together, moving at an angle of [N67E].
The vehicles left 40.0m skid marks behind.
15.334m of skid marks were on wet asphalt with a friction coefficient of 0.8.
24.6666m of skid marks were on dirt with a friction coefficient of 0.5.
Determine the initial velocity (before the crash) of vehicle one.
I am instructed to use kinematics and dynamics to solve this problem.
Homework Equations
Vf = Vi + 2ad
Fg = mg = weight = normal force
fk = µkFN
The Attempt at a Solution
I created a free body diagram but do not know how to approach the problem, any help is appreciated.
I have also searched this website for similar answers but non applied to my problem
