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?
A mass m slides up an incline (with = 32.1 degrees above the horizontal) until it stops momentarily because of friction. The coefficient of static friction between the mass and incline is 0.9; the coefficient of kinetic friction between the mass and incline is 0.4. At a given instant, the mass is moving with speed of 4.3 m/s up the incline. How far beyond this point along the incline will the mass move before it comes to a stop?
