A person gets in an elevator on the ground floor and rides it to the top floor of a building. Sketch a velocity-versus-time graph for this motion.
To draw: The velocity-versus-time graph.
Answer to Problem 1CQ
The velocity-versus-time graph is drawn.
Explanation of Solution
Given data:
A person gets in an elevator on the ground floor and rides it to the top floor of a building.
Explanation:
Normally when the elevator starts to function, initially the speed or velocity will be low and then gradually increases its speed. In the middle period of the elevator functioning, the speed becomes constant and at end period speed slows down and comes to rest.
The velocity-versus-time graph for the above scenario is shown in Figure 1.
Initially graph starts from zero, gradually increases. During middle period velocity remains constant showing horizontal line in the graph. During end period there will be gradual decrease and end at zero in the graph.
Conclusion:
Hence, the velocity-versus-time graph is drawn.

- 13.87 ... 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?
