## Homework Statement

I am working on my calc 3 project where she has given two parametric equations, one models the motion of a Ferris wheel and the other models an object being thrown to a person on the Ferris wheel.

OK so I have this parametric equation that models an object being thrown and I'll try to type this as clearly as possible.

r1(t)= <22-8.03(t-t0), 1+11.47(t-t0)-4.9(t-t0)^2>

The second equation is for the Ferris wheel

r2(t)= <15sin((pi*t)/10),16-15cos((pi*t)/10)

the t0 are t subscript 0 just for clarification. So I have that and it is asking me to find the speed and angle of inclination of the object when t=t0

I also want to make it clear that this question has to do with the first equation I only brought the second one in for completeness and in case I'm wrong and I actually need that one too.

## Homework Equations

just gave them

## The Attempt at a Solution

I've tried to plug in t for t0 and obviously that turns to 0 and then take an integral to get the equation that models velocity and then I would have to get the magnitude of that. However when I do that I get t showing up and I have no value for t or anything.

I've also tried to take the integral of the equation before plugging in for t0 but I am not sure how I would go about doing that since I have two variables in there.

So all in all I'm stuck and would appreciate some help.
