Textbook Question
Chapter 2, Problem 93TDI
Two balls, A and B, are released simultaneously from rest at the left end of the equal-length tracks, as shown.
(a) Which ball will reach the end of its track first?
(b) Does ball B roll faster along the lower part of track B than ball A rolls along track A?
(c) Is the speed gained by ball B going down the extra dip the same as the speed it loses going up near the right-hand end? Does this mean that the speeds of balls A and B will be the same at the ends of the tracks?
(d) So, overall, does ball A or ball B have the greater average speed? (Do you wish to change your answer to (a)?

Interplanetary Navigation. The most efficient way to send a spacecraft from the earth to another planet is by using a Hohmann transfer orbit (Fig. P13.87). If the orbits of the departure and destination planets are circular, the Hohmann transfer orbit is an elliptical orbit whose perihelion and aphelion are tangent to the orbits of the two planets. The rockets are fired briefly at the depar- ture planet to put the spacecraft into the transfer orbit; the spacecraft then coasts until it reaches the destination planet. The rockets are then fired again to put the spacecraft into the same orbit about the sun as the destination planet. (a) For a flight from earth to Mars, in what direction must the rockets be fired at the earth and at Mars: in the direction of motion, or opposite the direction of motion?
