A projectile launched vertically from the surface of the Moon rises to an altitude of 465 km.
Part A What was the projectile's initial speed?
Given is:-
The altitude of the projectile
or
Now,
we know that the gravitational acceleration constant of moon is
Using third equation of motion we get
by taking upward direction positive and plugging the values we get
(Note: - we know that at highest point the velocity will be
zero)
which gives us the initial speed of the procjectile
