To identify:The action that is permissible during graphical addition of vectors.
Answer to Problem 48A
Moving the vector
Explanation of Solution
Introduction:
A vector is a physical quantity which has both magnitude as well asdirection.
The length of vector indicates its magnitude.So, if the length of the vector is altered,the magnitude is changed. When the vector is rotated, its direction gets changed.In both the cases where the length of the vector is changed and the vector is rotated, the vector itself changes. But the vector can be moved easily while adding to another vector without changing its length and direction.
Conclusion:
Therefore, the permissible action is to move the vector without changing length and direction.

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? What about for a flight from Mars to the earth? (b) How long does a one- way trip from the the earth to Mars take, between the firings of the rockets? (c) To reach Mars from the…arrow_forward
