Explanation:
The weight of the car is equal to, ...........(1)
Where
m is the mass of car
g is the acceleration due to gravity
The normal or vertical component of the force is,
or
.............(2)
The horizontal component of the force is,
Taking ratio of equation (1) and (2) as :
or
Hence, this is the required solution.
To solve this problem we will apply the laws of Mersenne. Mersenne's laws are laws describing the frequency of oscillation of a stretched string or monochord, useful in musical tuning and musical instrument construction. This law tells us that the velocity in a string is directly proportional to the root of the applied tension, and inversely proportional to the root of the linear density, that is,
Here,
v = Velocity
= Linear density (Mass per unit length)
T = Tension
Rearranging to find the Period we have that
As we know that speed is equivalent to displacement in a unit of time, we will have to
Therefore the tension is 5.54N
