The approximate amount of thrust(force) you need to apply to the lander to
keep its velocity roughly constant is zero.
<h3>What is Newton's second law of motion?</h3>
Newton's second law of motion states that the acceleration the force acting
on the object is directly proportional to its rate of change of momentum.
F = m a
If the object is moving with uniform velocity, it simply means that the
acceleration is zero, and the corresponding force will also be zero.

Effort force and Resistance force
2^4/2^7 = 16/128 = 0.125
(1/2)^3= 0.125
1/8= 0.125
a and f are equivalent
