Answer:
Yes
Explanation:
If an object is moving to the left and begins to experience an acceleration to the right, the object will eventually slow its leftward motion, stop, and begin moving to the right.
Explanation:
It is given that,
Mass of object 1,
Initial speed of object 1,
Mass of object 2,
Initial speed of object 2,
The momentum of an object in case of elastic collision remains conserved. It is given by :
.............(1)
For elastic collision, the coefficient of restitution is equal to 1. It is given by :
...............(2)
On solving equation (1) and (2) we get :
Hence, this is the required solution.
Answer:
Explanation:
stiffness k = 160
m = 10
angular frequency ω =
=
= 4
ω = 4
Let x = 4 - A sinωt
when t = 0
x = 4 in
when t = 2 s , x = - 4
- 4 = 4 - A sinωt
8 = A sin 4 x 2
8 = A sin8
A = 8 / sin 8
= 8 / .989
= 8.09 in .
x = 4 - A sinωt
dx / dt = - Aω cosωt
v = - Aω cosωt
for t = 0
v = - Aω
= - 8.09 x 4
= - 32.36 in / s
initial velocity v = - 32.36 in /s
displacement x for t = 4s
x = 4 - 8.09 sin 4 x 4
= 4 - 8.09 sin 16
= 4 - 8.09 x - .2879
= 4 + 2.33
= 6.33 in.
c ) Amplitude of vibration A = 8.09 in .as calculated above .
Salt is made in in the water the seaweeds have slat on them of you let the seaweeds dry you can see the salt on them.
This is more chemistry. But it is a process called fractional distillation, and it basically separates the long chained hydrocarbons from the short chained hydrocarbons through separation dependant on the boiling point of the crude oil.
