I believe the correct gravity on the moon is 1/6 of Earth.
Take note there is a difference between 1 6 and 1/6.
HOWEVER, we should realize that the trick here is that the
question asks about the MASS of the astronaut and not his weight. Mass is an
inherent property of an object, it is unaffected by external factors such as
gravity. What will change as the astronaut moves from Earth to the moon is his
weight, which has the formula: weight = mass times gravity.
<span>Therefore if he has a mass of 50 kg on Earth, then he will
also have a mass of 50 kg on moon.</span>

wanted to pull out a particular issue from a pile of magazines. First,
she tried pulling slowly, and the whole pile began to move. Then she
tried pulling quickly, and the issue she wanted came out without the
pile moving. The pile did not move because of the?
a. larger force Alicia applied
b. smooth surface of the magazines
c. inertia of the pile and friction <--- *** Answer ***
d. friction between the magazines
(If this is your question)
Hope this helps :p

Given :
Initial velocity, u = -15 m/s.
Acceleration , a = 2 m/s².
Time taken to applied brake, t = 2.5 s.
To Find :
The velocity of the car at the end of the braking period.
How far has the car moved during the braking period.
Solution :
By equation :
Now, distance covered by car is :
Hence, this is the required solution.
