Solving a Robot Probe Homework Problem on Mars

In summary, a camera is dropped by a robot probe from a 239 m high cliff on Mars, where the freefall acceleration is -3.7 m/s^2. The task is to find the velocity with which the camera hits the ground and the time it takes to hit the ground. Using the equation vf^2= vi^2+2ad, we can calculate a negative final velocity and determine the time required for the camera to hit the ground.

Homework Statement


a robot probe drops a camara off the rim of a 239 m high cliff on mars, where the freefall acceleration is -3.7 m/s^2. a. fiind the velocity wl which the camara hits the ground. b. find the tiime required for it to hit the ground.


Homework Equations



vf^2= vi^2+2ad

The Attempt at a Solution



a=-3.7m/s^2
d=239m
vi=0m/s
vf=? ned to find
t=?

vf^2=vi^2+2ad
vf^2=-1786.6

d is actually -239m since it's falling. which means starting from 239 m and falling down to 0m so the change is -239m. the vf you will then calculate is actually negative like the acceleration since, again, it is falling downwards on the y axis

Looks good except your displacement should be negative, [tex]\Delta d=0-239m[/tex]

That will make your value for [tex]v_f^2[/tex] positive and you should be able to proceed.

tyvm! but i want to just ask 1 more question... so then will the final velocity be negative?b/c it is falling
 
  • #5
yes the vf will be negative, like i said in my previous reply >_>
 

Related to Solving a Robot Probe Homework Problem on Mars

1. How do you design a robot probe for Mars?

Designing a robot probe for Mars involves a complex process that includes considering the mission objectives, budget, and technology constraints. The probe must be able to withstand the extreme conditions on Mars, such as temperature fluctuations and dust storms, while also being equipped with the necessary instruments and communication systems to collect and transmit data back to Earth.

2. What challenges do you face when solving a homework problem for a robot probe on Mars?

Some of the main challenges when solving a homework problem for a robot probe on Mars include the limited amount of information available about the Martian environment, the time delay in communication between Earth and Mars, and the need for the probe to be autonomous and able to make decisions on its own.

3. How do you ensure the accuracy of the data collected by the robot probe on Mars?

To ensure the accuracy of the data collected by the robot probe on Mars, extensive testing and calibration of the instruments must be conducted before the probe is launched. Additionally, the probe may be equipped with redundant systems and backup instruments to minimize the risk of data errors.

4. What role does artificial intelligence play in solving homework problems for robot probes on Mars?

Artificial intelligence plays a crucial role in solving homework problems for robot probes on Mars. It allows the probe to make decisions and adapt to unexpected situations without constant human intervention. AI also helps with data analysis and interpretation, making it easier to identify important findings and trends.

5. What are the potential benefits of using robot probes to explore Mars?

Robot probes offer several benefits for exploring Mars, such as the ability to collect data from multiple locations on the planet, access hard-to-reach areas, and operate for extended periods of time. They also eliminate the need for human astronauts to physically travel to Mars, reducing the risk and cost of manned missions.
