(a) Find the magnitudes of the forces F1 and F2 that add to give the total force Ftot shown in Figure 4.35. This may be done either graphically or by using trigonometry. (b) Show graphically that the same total force is obtained independent of the order of addition of F1 and F2. (c) Find the direction and magnitude of some other pair of vectors that add to give Ftot. Draw these to scale on the same drawing used in part (b) or a similar picture.

Find the following for path C in Figure 3.58: (a) the total distance traveled and (b) the magnitude and direction of the displacement from start to finish. In this part of the problem, explicitly show how you follow the steps of the analytical method of vector addition.

A ferry transports tourists between three islands. It sails from the first island to the second island, 4.76 km away, in a direction 37.0 north of east. It then sails from the second island to the third island in a direction 69.0 west of north. Finally it returns to the first island, sailing in a direction 28.0 east of south. Calculate the distance between (a) the second and third islands and (b) the first and third islands.

The average distance between Earth and the Sun is 1.51011m . (a) Calculate the average speed of Earth in its orbit (assumed to be circular) in meters per second. (b) What is this speed in miles per hour?
