The value is
Explanation:
From the question we are told that
The first position of the fulcrum is x = 49.7 cm
The mass attached is
The position of the attachment is
The second position of the fulcrum is
Generally the sum of clockwise torque = sum of anti - clockwise torque
So
Here CWT stands for clockwise torque
So

Answer:
Explanation:
Using the equation of motion to get the acceleration due to gravoty of the rock on the planet.
S = ut+ 1/2at² where;
S is the distance of the rock above the surface of the planet = 100m
u is the initial velocity = 15m/s
a is the acceleration due to gravity
t is the time taken by the rock to reach the ground = 10s
Since the rock is thrown upward the acceleration due to gravity will be negative i.e a= -g
The equation becomes S = ut- 1/2gt²
Substituting the given value to get the time t
100 = 15(10)- 1/2g(10)²
100 = 150-50g
100-150 = -50g
-50 = -50g
g = -50/-50
g = 1m/s²
<em>Hence the acceleration due to gravity of the rock when it is on Planet XX is 1m/s²</em>
