Answer:
The speed of the vehicle moving along its descent path is .
Explanation:
It is given in the problem that a descent vehicle landing on the moon has a vertical velocity toward the surface of the moon of 37.7 m/s. At the same time, it has a horizontal velocity of 54.6 m/s.
The expression for the velocity of the vehicle moving along the descent path is as follows;
Here, is the vertical velocity of the vehicle landing on the surface of the moon and is the horizontal velocity of the vehicle landing on the surface of the moon.
Put and in the above expression.
Therefore, the speed of the vehicle moving along its descent path is .
The force of gravity starts to decrease since your traveling away from the atmosphere.
Answer:
20 m/s
Explanation:
Given:
Δy = 0.02 km = 20 m
v₀ = 0 m/s
a = 9.8 m/s²
Find: v
v² = v₀² + 2aΔy
v² = (0 m/s)² + 2 (9.8 m/s²) (20 m)
v = 19.8 m/s
Rounded to one significant figure, the final velocity is 20 m/s towards the ground.
