a.) A1 = π (d1/2)^2
b.) A1 = π(1.85cm/2)^2 = 2.688cm^2
c.) Q1 = A1*v1
d.) v1 = Q1 / A1 = 860 cm^3/s / 2.688cm^2 = 319.94 cm/s = 0.31994 m/s
e.) A2 = (A1 * v1)/v2
f.) A2 = (2.688cm^2 * 0.31994 m/s)/10.8m/s = 0.07963 cm^2
it is the instantaneous velocity as a projectile leaves the barrel
Yes, but only for a single instant in time. When you throw a golf ball or a rock straight up, it has the constant downward acceleration of gravity from the moment it leaves your hand, but its velocity is certainly not constant. The velocity steadily decreases until the peak of the toss, and then it switches from upward to downward velocity. At the very peak, the velocity is zero for an instant.
The Answer Is: 4 feet per second.
The horizontal velocity will be equal to the translational velocity of the ball right before it falls off the table. ============================== When we do exercises that deal with the behavior of the ball after it leaves the edge of the table, we always ignore air resistance. When we do that, the horizontal component of velocity remains constant forever, or at least until the ball hits something.
As far as we can tell, it doesn't. Momentum is defined as (mass) times (velocity). There appear to be only two ways in which momentum can decrease: either the mass has to magically evaporate, or else the velocity has to decrease. Since mass conservation is a nearly fundamental law of nature, that leaves us with velocity as the only way to change the momentum of a moving body.

positive acceleration
Phloem
Yes
yes it is because it is attached to the tree and the tree is alive, also branches normally have leaves on them and leaves are living organisms and they transfer the photosynthesis through the branches to give it to the trunk of the tree
One leaf attached to a stem.
I think its the xylem
No because the astronaut's relative velocity will be approximately the same as that of the spacecraft.
No, love is when you become emotionally attached to someone
aspen
Petunia leaves are sessile which means they grow without a leaf stem attached to the main stem. The leaves are opposite.
the node, leaves are attached to the node by the petiole
