QUESTION:
Which of the speed-versus-time plots in Figure 2–37 (b) correctly represents the speed of the Apollo 15 lander?
A B C D
ANSWER:
Step 1 of 2
The acceleration of the lander is in the downward direction.
That is acceleration is in the same direction to that of initial velocity, so speed keeps on increasing.
The acceleration of the lander is constant, so the speed-time graph will be a straight line with increasing speed.
