have you noticed the U.S. is moving away from science and more toward radical religious beliefs?

Why our we falling for this. Stem cells, eco-science, is being replaced with fairy tails of a god, or god's. Can we be as primitive as that? because we do not understand it, dose not make it magic.

A projectile is shot from the edge of a cliff h = 245 m above ground level with an initial speed of v0 = 145 m/s at an angle of 37.0° with the horizontal

how long would it take the projectile to hit point P at ground level.
s
How would I find the range X of the projectile motion, would it be the horizontal component?
km
At the instant just before the projectile hits point P, find the horizontal and the vertical components of its velocity (take up and to the right as positive directions).
I got 115.8 m/s (horizontal component)
I got 87.26 m/s (vertical component)-is this right?
What is the the magnitude of the velocity?
m/s. Is magnitude the same as velocity?
What is the angle made by the velocity vector with the horizontal?
° (below the horizontal)

I don't get any of this. I don't know what they mean by range. I don't understand what they are asking me to do.
Can someone explain this to me or show me their work?

Negative tension possible?

If tension can be expressed as force (F=ma), is it possible to yield a negative tension value under the law of physics? Example, you have a negative acceleration multiplied with a mass that gives you a negative number.

physics help?

A box of books weighing 319 N is shoved across the floor by a force of 48s N exerted downward at an angle of 35 degrees belown the horizontal.
a) ifthe coefficient of kinetic friction between teh box and the floor is 0.57, how long does it take to move the box 4 m, starting from rest
b) if coefficient of kinetic friction between the box and the floor is 0.75, how long does it take to move the box 4 m, starting from rest?

A 3 kg block starts from rest a the top of a 30 degree incline and accelerates uniformly down the incline, moving 2 m in 1.5 s
a) Find the magniutde of the acceleration of the block
b) find th coefficient of kinetic frction between the block and the incline.
c)Find the magnitude of the frictional force acting on the block
d) find the speed of the block after it ha slid a distance of 2 m
