A playground tire swing has a period of 2.0 s on Earth. What is the length of its chain?
1 answer:
Answer:
Length of the chain, l = 0.99 m
Explanation:
Given that,
A playground tire swing has a period of 2.0 s on Earth i.e.
T = 2 s
We need to find the length of this chain. The relationship between the length and the time period is given by :
Where
l = length of chain
g = acceleration due to gravity
l = 0.99 meters
So, the length of the chain is 0.99 meters. Hence, this is the required solution.

<h3>What is friction force?</h3>
Opposition forces on the surface cause heat loss during the motion of an object known as the friction force.
Given data:
m(mass)= 10.0-kg
Θ (Inclination angle)=25.0o
Coefficient of sliding friction,=0.520
Coefficient of static friction,
The friction force, F=?
Resolve the force in the inclined plane;
Hence, the frictional force while the mass is sliding will be 46.2 N.
