Answer:
Explanation:
We know that the gravity on the surface of the moon is,
<u>Gravity at a height h above the surface of the moon will be given as:</u>
..........................(1)
where:
G = universal gravitational constant
m = mass of the moon
r = radius of moon
We have:
- is the distance between the surface of the earth and the moon.
Now put the respective values in eq. (1)
is the gravity on the moon the earth-surface.
Answer:
50 kg·m/s.
Explanation:
Momentum can be calculated using p = mv. (Let p represent momentum, m represent mass, and v represent velocity.)
Plugging our terms in, we have p = 5 kg * 10 m/s. This gives us p = 50 kg·m/s as an answer.
Velocity is the displacement of an object during a specific unit of time. Explanation: The standard unit of velocity is metre per second.
