Answer:
12.1 seconds
Explanation:
t = time duration
u = initial speed
v = final speed = 0
s = distance = 120 m
a = lunar gravity acceleration = 1.67 m/s²
Motion equation
The rock takes 12.1 seconds to reach the bottom of the crater.
Answer:
Explanation:
The first number is .
The second number is .
We must multiply these two numbers together.
In scientific notation:
Therefore, this is the solution you are looking for.
To tackle this issue, we will utilize concepts related to gravity based on Newtonian definitions. To find this value, we'll apply linear motion kinematic equations to determine the required time. Our parameters include:
Comet mass
Radius
The rock is released from a height 'h' of 1 m above the surface.
The relationship for gravity's acceleration concerning a body with mass 'm' and radius 'r' is described by:
Where G represents the gravitational constant and M denotes the mass of the planet.
Now, let’s compute the time value.
Ultimately, the time for the rock to hit the surface is t = 87.58s.
