If a constant force is applied on a body, the body moves with constant acceleration.
True. You're suppose to answer true or false, right?
T = (v-0)/a
t = (45.5)/(9.8)
= 4.64m/s.
hope this helps :)
There are two main effects of deforestation on global warming: 1) the "slash and burn" technique used to clear the forest releases carbon dioxide into the atmosphere, and 2) destruction of living trees reduces the amount of photosynthesis, a process that removes carbon dioxide from the atmosphere and stores it in the plants as carbon. Carbon dioxide is one of the major gases contributing to global warming, and increasing its concentration will affect the amount of warming that occurs.
Answer:
The time constant is
Explanation:
From the question we are told that
The spring constant is 
The mass of the ball is 
The amplitude of the oscillation t the beginning is 
The amplitude after time t is 
The number of oscillation is 
Generally the time taken to attain the second amplitude is mathematically represented as
Here T is the period of oscillation

=> 
=> 
Generally the amplitude at time t is mathematically represented as

Here a is the damping constant so
at
, 
So

=> 
taking natural log of both sides
=>
=> 
Generally the time constant is mathematically represented as
=>
=>
