a quaterback throws a football towards a reciever with an initial speed of 22m/s, at an angle of 34 degrees above the horizontal. At that instant, the reciever is 21 m from the quarterback. The acceleration of gravity is 9.8 m/s ^2. WIth what constant speed should the reciever run in order to catch the football at the level at which it was thrown? Answer in units of m/s.

A projectile of mass 0.552 kg is shot from a
cannon, at height 7 m,
with an initial velocity vi having a horizontal
component of 5 ms.
The projectile rises to a maximum height of
Y above the end of the cannon's barrel and
strikes the ground a horizontal distance X
past the end of the cannon's barrel.
The acceleration of gravity is 9.8 ms^2 :

Determine the vertical component of the
initial velocity at the end of the cannon's bar-
rel, where the projectile begins its trajectory.
Answer in units of ms.

Determine the maximum height Y the pro-
jectile achieves after leaving the end of the
cannon's barrel. Answer in units of m.

Find the magnitude of the velocity vector
when the projectile hits the ground. Answer
in units of ms.

Find the magnitude of the angle (with repect
to horizontal) the projectile makes when im-
pacting the ground. Answer in units of degree.

Find the range"x" of the projectile. Answer
in units of m.

Hi,

Besides that, we also know that love or sorrow affect our health.
So, emotions or thoughts can affect our health and it shows that mind is the one which does all that.

But how can it do that?
Is there a scientific explanation?

PLEASE DO NOT ANSWER WITH LINKS.
PLEASE SHOW YOUR SOURCE.

Thank you very much.
