A young boy pulls a 18 kg box with a force of 45 N directed at an angle of 30 degrees below the axis. What is the x component of the force? What is the acceleration of the box? What is the vertical component of the force? What is the force of gravity on the object? What is the normal force acting in the object?

Asailboat is traveling to the right when a gust of wind causes the boat to accelerate leftward at 2.5m/s2 for 4s. after the wind stops, the sailboat is traveling to the left with a velocity of 3.0m/s.assuming the acceleration from the wind is constant, what was the initial velocity of the sailboat before the gust of wind? answer using a coordinate system where rightward is positive.
