  Answer)
  Velocity of car = 130 km/hr = (5/18)×130 mts/sec
  = 36.11 m/s
  Upgradient n = 3% = 0.03
  Skid Marks leading to pedestal = 90 mts
  Coefficient of friction f = 0.35
  (a)
  If the car had not hit the pedestal
  Distance of skid = (V^2)/(2g(f-n)) = ((36.11)^2)/(2*9.81(0.35-0.03)) = 207.7 metres
  total distance of skid = 207.7 mts
  It would have further skidded a distance of 207.7 - 90 = 117.7 mts
  (b)
  speed at impact
  from the equation V^2 - U^2 = 2g(f-n)S
  Initial velocity = 36.11 m/s
  Distance S = 90 meters
  f= 0.35 n= 0.03
  (36.11)^2 - U^2 = 2×9.81×(0.35-0.03)×90
  U^2 = 1304 - 565= 739
  U = 27.2 m/s
  Hence velocity of car at impact = 27.2 m/s = 97.9 km/hr
  (c)
  Actual stopping sight distance = braking distance =
  207.7 mts
