A boat has a mass of 5840 kg. Its engines generate a drive force of 3310 N due west, while the wind exerts a force of 860 N due east and the water exerts a resistive force of 1210 N due east. Take west to be the positive direction. What is the boat's acceleration. with correct sign?

Three people pull simultaneously on a stubborn donkey. Jack pulls eastward with a force of 94.5 N,94.5 N, Jill pulls with 88.1 N88.1 N in the northeast direction, and Jane pulls to the southeast with 181 N.181 N. (Since the donkey is involved with such uncoordinated people, who can blame it for being stubborn?)   Find the magnitude of the net force the people exert on the donkey.   What is the direction of the net force? Express this as the angle from the east direction between 0°0° and 90°,90°, with a positive sign for north of east and a negative sign for south of east.

A contestant in a winter games event pushes a 37.0 kg block of ice across a frozen lake as shown in the figure. 25°. The coefficient of static friction is 0,1 and the coefficient of kinetic friction is 0.03.

A 43.2 kg video cart is rolled down a hallway. It is accelerated at 0.30 m/s^2. If a force of 27 N is applied to move the cart, what force of friction do the wheels have against the floor?

An SUV containing 5 passengers has a mass of 3500 kg. It has a driving force of 2500 N directed west on a perfectly horizontal road. The surface of the road exerts a resistive force of 500 N due east. At the same time, a strong wind is blowing a force of 500 N due east in the opposite direction of the car's drive force. Does the car have any acceleration? If yes, then what is the magnitude and direction of the car's acceleration?

A package of weather instruments is attached to a weather balloon. The package has a mass of 12.4 kg. The system is released vertically from rust. The weather balloon provides a constant lift force of 122.5 N for 6 minutes. calculate the magnitude and direction of the instruments acceleration during the first six minutes of flight ignore air resistance.

A truck is towing a 10,000-N car at a constant speed up a hill that makes an angle of a=5.0° above the horizontal. A rope is attached from the truck to the car at an angle ß=10.0° above the horizontal. (Friction is negligible.) (a) Draw a free-body diagram showing the forces acting on the car. Indicate the angle that each force makes either with either the vertical or horizontal direction. (b) What is the tension in the rope?
