Given:
= 12 m/s
Time = 15 s
To find:
Deceleration = ?
Formula used:
Deceleration is given by,
a = 
Solution:
Acceleration of the body is rate of increase of velocity. Deceleration of the body is negative acceleration i. e rate of decrease of velocity.
Thus, deceleration of the body is given by,
a =
where a is the deceleration of the body
v is the velocity
is rate of change of velocity
t is the time
a = 
a = 0.8 m/ 
Thus, deceleration is 0.8 m/ .
It says that the force of a spring is always opposite to the direction in which you stretch it or compress it. (the direction of 'x')
In other words, a spring that's disturbed always tries to put itself back to it's normal length, where x would be zero.
Nuclear energy is released during: fission. radioactive decay. man-induced splitting of atoms. Match the basic components of a nuclear reactor with their descriptions. 1. slows down neutrons -> moderator. 2. absorb emitted neutrons -> control rods.
Air pollution level is higher in Location B, because poisonous fumes are produced when coal burns.
In a food web the energy is originated from the SUN.
