Question

Car  1  was  sitting  at  rest  when  it  was  hit  from  the  rear  by  car  2  of  identical  mass.     Both  cars  had  their  breaks  on  and  they  skidded  together  6  m  in  the  original   direction  of  motion.    If  the  stopping  force  is  ~  0.7  ´  (combined  weight  of  the  cars)  ,   i.e.,   µ  =  0.7,    find  the  approximate  speed  of  car  2  just  before  the  collision  took   place.          [18.14  m/s]

Answer 2

Answer:

Both cars had their breaks on and they skidded together 6 m in the original direction of motion. If the stopping force is ~ 0.7  (combined weight of the cars) , i.e., combined weight of the cars) , i.e.,  = 0.7, find the approximate speed of car 2 just before the collision took place.
