A projectile launched vertically from the surface of the Moon? rises to an altitude of 365 km. What was the projectile's initial speed?

Solution 52P

Step 1 of 3:

A projectile is launched from the surface of Moon and reaches an altitude equal to h and the final velocity v2 becomes zero. Now we are going to find the initial velocity v1 of the projectile.

The acceleration due to gravity of Moon gm = 1.62 m/s2

The radius of Moon R = 1.74 x 106 m

The altitude reached by the projectile h = 365 km = 3.65 x 105 m
