Question

MEDAL - TRUE or FALSE
The horizontal distance, in feet, traveled by a projectile can be modeled by the equation..

h = ((v0^2)/16) sinθcosθ

..where θ is the initial angle and v0 is the initial velocity. This simplifies to

h = ((v0^2)/32) sin(2θ) .

Answer 1

Just curious, does the denominator (32) have any units of measurement? It seems to me like the units would come out (assuming we're using feet per second) would be \[\frac{ ft^{2} }{ s ^{2} }\] and I'm not sure that means anything. Certainly wouldn't be distance.

Answer 2

I can't find the symbol for v0^2

Answer 3

but you knew what I was talking about, right?

Answer 4

I'm not really sure. It didn't look like any kinematics equation I did in physics class, was just trying to make sense of the equation. Velocity is a distance per time, in this case, it's probably ft/sec. If you square that you'll get ft^2/s^2, which doesn't relate to a distance. Typically angles don't have a unit of measurement. It doesn't say anything about the denominator being anything? Maybe acceleration?

Answer 6

the answer is TRUE

Answer 7

LoL, well, there you go. Sorry I wasn't more helpful.

Answer 8

Its okay! :) Keep it up though
