A car with snow tyres (m=1500 kg) is sliding down an icy hill with a slope of 15º at an initial speed of 8 m/s.) The coefficient of kinetic friction is 0.4.
a. What is the stopping distance
b.After sliding 12 m what is the momentum of the car?
c. At this point of having travelled 12m the car collides into another car (m=1000 kg) travelling 3 m/s in the same direction down the slope and they are stuck together. What is the velocity just after impact?
