Answer:30.2m
Explanation:
Let be the displacement of Susan.
Let be the initial velocity of Susan.
Let be the acceleration of Susan.
Let be the time taken by Susan.
Given that Susan starts from rest.
From the given information we can assume that no additional forces are acting on the sled.So,the acceleration is constant.
As we know from the equations of motion,
Given that,
So,
Answer:
0.0052 m
Explanation:
g = Acceleration due to gravity = 9.78 m/s²
Time period
The length of the pendulum is 0.0052 m
