Answer:
(2.5,0)
Explanation:
The particle can be described by the following equations:
For R = 2.5, ω = 2 and t = 0:
The center of the circle would be at point (2.5,0)
Answer:
Part a)
Time to reach the maximum height is given as
B)
Maximum height of the bullet is
C)
Horizontal range of the bullet is
Part d)
Final velocity of the bullet is v = 600 m/s at 30 degree
Explanation:
A) As we know that velocity of the bullet is
v = 600 m/s
So we have
Now time to reach the maximum height is given as
B) As we know that the object have zero final speed in y direction
C)
Now the horizontal displacement of the object in total time of flight is known as range of projectile
So we have
Part d)
As we know that the final height is same as that of initial So it will strike the ground at same velocity as that of initial velocity
So we have
v = 600 m/s at 30 degree
Well it is due to the fact that when you
submerge
the wooden block into the cylinder. The displacement of water from the initial-measurement (before the block was submerge) to finial-measurement will be the volume of wooden block.
Note: In cases of floating objects. You can always add a sinker to it to submerge the object.
But
you will need to take into account the volume of the sinker and minus off the added volume of sinker.
Answer:
Atom, smallest unit into which matter can be divided without the release of electrically charged particles.
an element is a pure substance which cannot be broken down by chemical means
