For the following exercises, consider a small boat crossing a river.

444.

If the boat velocity is 55 km/h due north in still water and the water has a current of 22 km/h due west (see the following figure), what is the velocity of the boat relative to shore? What is the angle θθ that the boat is actually traveling?

This figure is an image of overtop of a boat. There is a line segment from the back of the boat. It is labeled “5 k m/h r.” This line segment has another line segment perpendicular. It is labeled “2 k m/h r.” There is another line segment making a right triangle with the other two. The angle between the line segments from the boat is theta.
445.

When the boat reaches the shore, two ropes are thrown to people to help pull the boat ashore. One rope is at an angle of 25°25° and the other is at 35°.35°. If the boat must be pulled straight and at a force of 500N,500N, find the magnitude of force for each rope (see the following figure).

This figure is overtop of a boat. From the front of the boat is a horizontal vector. It is labeled “500 N.” There are two other line segments from the boat. The first one forms an angle with the horizontal vector of 35 degrees above the vector. The second line segment forms an angle of 25 degrees below the vector.
446.

An airplane is flying in the direction of 52° east of north with a speed of 450 mph. A strong wind has a bearing 33° east of north with a speed of 50 mph. What is the resultant ground speed and bearing of the airplane?

447.

Calculate the work done by moving a particle from position (1,2,0)(1,2,0) to (8,4,5)(8,4,5) along a straight line with a force F=2i+3jk.F=2i+3jk.

The following problems consider your unsuccessful attempt to take the tire off your car using a wrench to loosen the bolts. Assume the wrench is 0.30.3 m long and you are able to apply a 200-N force.

448.

Because your tire is flat, you are only able to apply your force at a 60°60° angle. What is the torque at the center of the bolt? Assume this force is not enough to loosen the bolt.

449.

Someone lends you a tire jack and you are now able to apply a 200-N force at an 80°80° angle. Is your resulting torque going to be more or less? What is the new resulting torque at the center of the bolt? Assume this force is not enough to loosen the bolt.
