A robotic scientific lander on Mars launches a soil-sample capsule vertically upwards from the surface. The capsule returns to the landing pad 6.4 s after launch. The acceleration due to gravity on Mars is 3.7 m s-2 and atmospheric drag is negligible.
What is the total distance travelled by the capsule?
