A simple pendulum consists of a 2 kg bob attached to a 1.5 m long string. How much time (in s) is required for this pendulum to
Charra [1.4K]

Answer:

6.15 s

Explanation:

The period of a simple pendulum is given by the equation

T=2\pi \sqrt{\frac{L}{g}}

where

L is the length of the pendulum

g is the acceleration of gravity

For the pendulum in this problem,

L = 1.5 m (length)

g=9.8 m/s^2 (acceleration due to gravity on Earth)

Therefore, its period is

T=2\pi \sqrt{\frac{1.5}{9.8}}=2.46 s

And therefore, the time taken for the pendulum to complete 2.5 oscillations is equal to 2.5 times the period:

t=2.5T=(2.5)(2.46)=6.15 s

I need help with this one ! <br><br>Explanation needed ~ ​
weqwewe [10]

Answer:

Please find here some hints :

Rule. Newton’s second law, or fundamental principle of dynamics, mentions that a resultant force exerted on an object is always equal to the product of the mass of that object by its acceleration. ... Each force applied to an object causes this object to accelerate in the direction of the force applied.

Is acceleration a force?

The acceleration force, sometimes called the inertia force, is the vehicle’s resistance to speed variations. It holds you back when you increase your speed and pushes you back when you slow down.
