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?

Two penguins are having fun sliding on an icy, nearly frictionless slope, that rises above level ground at an angle of 11 degrees. One penguin has mass 15 kg while the other has mass 5 kg. At one point, the heavier penguin starting from rest, begins sliding frictionlessly down the slope. At the same time, the lighter penguin, starting from higher up the slope launches itself downward. It catches up to the heavier penguin after 2 seconds, both penguins then...

A dog sled is sliding down a hill. The sled starts from a height of 25 m and has a weight of 66 kg. It collides with a person at the bottom of the hill. The person weighs 72 kg. The collision is completely inelastic. Friction can be ignored due to icy conditions. Determine the speed of the sled and the person after the collision Show all steps for full marks.

A 20-kg rocket sled is sliding up a 30 degree, 10-m high snow ski jumping hill from rest with constant thrust. The kinetic friction coefficient between the sled and snow is 0.2. The engine is turned off when the sled leaves the hill and it lands 50-m away from where it left the hill at ground level. The drag due to air resistance is negligible. What is the magnitude of thrust of the rocket sled? Edit: This is the question...
