Question

what does scos or ssin mean?!?!?!?!

Answer 1

Are those s*cos and s*sin? s might be a coefficient.

Answer 2

Are you doing things with vectors and parametric equations? s could be a parameter.

Answer 3

It's definitely not a coefficient but it's for a projectile problem

Answer 4

Does the letter 's' represent anything else in the problem?

Answer 5

no it's used like this "The initial velocity is equal to the final velocity horizontally because there is zero acceleration horizontally (v₀ = v = 89.0m/scos54.0° = 52.3m/s).The horizontal range is:"

Answer 6

Oh!, the s is in the denominator of the unit for velocity m/s.

Answer 7

oh my goodness you're a genius!

Answer 8

It should be written like this:
\[\large v = 89.0\frac{m}{s}*cos(54.0º)\]

Answer 9

how did I miss that wow

Answer 10

Thank you!!

Answer 11

You're welcome. I'm glad it didn't turn out to be 3-dimensional parametric vector equations like I first thought.
