1. The problem statement, all variables and given/known data Car 1 travels 50km/hr Car 2 travels 100km/hr The Cars are 45m apart Car 1 slams on brakes and stops in 8m a) Calculate deceleration of Car 1? (Car 1 has the same deceleration as Car 2) b) Use deceleration to find the distance it took Car2 to stop? c) Did the cars hit? The attempt at a solution Car 1 = 50 km/hr = 13.89 m/s Car 2 = 100 km/hr = 27.78 m/s a) Vf^2-Vi^2 = 2a(Delta x) 0 - 13.89^2 = 2a(8) -192.932=16a a= -12.05 m/s^2 b) 0-27.78^2=2(-12.05)x -771.7=-24.1x Distance it took Car2 to stop is = 32 m c) 45-32= 13m apart IS THIS RIGHT?
