Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

Cara is skiing down a hill. Her total mass (including the skis) is 70.4 kg. When she reaches the bottom of the ski slope, and the ground becomes level, she is moving at 6.22 m/s. The coefficient of friction between her skis and the snow is 0.114. How fast will Cara be moving 2.95 seconds after reaching the bottom of the slope? 1.12 m/s 3.30 m/s 2.92 m/s 2.16 m/s
The engines of a tanker broke down and the wind pushes the ship with a constant speed of 1.5 m / s straight towards a reef. When the boat is 500 m from the reef, the wind stops and the engineer manages to start the engines. The rudder is stuck, so the only option is to try to accelerate backwards. The mass of the ship and its cargo is 3.6 x 107 kg and the engines produce a net horizontal force of 8 x 104 N. The hull can withstand impacts at a speed of 0.2 m / s or less. The retarding force that the water exerts on the hull of the ship can be neglected. a) The equation of motion that corresponds to the horizontal component is? b)The acceleration of the ship is equal to? c) If the reef does not exist, the vessel, before stopping, travels what distance?

Under the influence of its drive force, a snowmobile is moving at a constant velocity along a horizontal patch of snow. When the drive force is shut off, the snowmobile coasts to a halt. The snowmobile and its rider have a mass of 138 kg. Under the influence of a drive force of 240 N, it is moving at a constant velocity whose magnitude is 5.44 m/s. The drive force is then shut off. Find (a) the distance in which the snowmobile coasts to a halt and (b) the time required to do so.
