I need help with a physics problem. My textbook doesnt seem to explain how to do this one.?

Question

The muzzle velocity of an armor-piercing round fired from an M1A1 tank is 1770 m/s (nearly 4000 mph or mach 5.2). A tank is at the top of a cliff and fires a shell horizontally. If the shell lands 6520 m (horizontally away) from the base of the cliff, how high is the cliff? Show work.

Answer 1

Ignoring air resistance:
t = D/r
t = 6520/1770
t = 3.68362sec
s = (1/2)gt^2
s = (1/2)(9.8)(3.68362)^2
s = 66.49m

Answer 2

i'm with gin in this one. Your textbook in all threat explains each and every thing. It in all threat explains the physics in comprehensive element. yet, my guess in keeping with a terrific variety of physics scholars, you're in all threat searching for an equation to plug into. And that may not be interior the e book. Why... you're predicted to assessment the physics and then derive in spite of equations you may remedy the subject. it somewhat is the way real physics and real physicists do it. it somewhat is the way the A scholars do it, too. So what's the physics to your subject. the 1st merchandise is the definitions. this is real of any and all sciences; study the definitions, this is the place each and every thing else comes from. And for you, you elect the definition of speed. And as that definition makes use of it, you besides would elect the definitions of displacement and distance. finally, term; you will be clean on what it somewhat is besides. as quickly as you study the definitions above, you may derive in spite of equations you may remedy this subject. study the physics.

Answer 3

Your textbook isn't going to explain to you how to do every possbile kind of problem; it's going to explain and demonstrate concepts. Your job it to be able to analyze new situations in terms of those concepts.

go ask a white man
i heard they are so smarrrrrrt
especially blondes
