How did Sengupta slow down the rover during its descent to Mars?

• Using only a heat shield

• Using a combination of a heat shield, parachute, and additional rockets

• Using only a parachute

• Using only additional rockets

Which of the following is an example of persistence as mentioned in the text?

• Using reasoning to develop the mechanism to deliver the lander onto the surface of Mars

• Going through six different designs and 76 pyrotechnic devices

• Forming new ideas, or images or concepts of external objects not present to the senses

• Using the basic laws of physics to design the parachute needed to land the rover

What is the formula to calculate average acceleration?

• A = v f - v i / t

• A = v i + v f / t

• A = v i - v f * t

• A = v i * v f / t

• -6,726 N

• 5,300 N

• 0 N

What could cause the forces to change slightly during the landing on Mars?

• Variation in the rover's mass

• Atmospheric conditions on Mars

• Change in the rover's shape

• The time taken to stop the rover

What is the role of imagination in the Mars landing mission?

• Going through six different designs and 76 pyrotechnic devices

• Using reasoning to develop the mechanism to deliver the lander onto the surface of Mars
