I think the first answer is (-3,4) and the second is 60(-3,4) = (-180,240), recheck your calcs and then do the third question again.
You should do a dimensional analisys: for x, . To input t in minutes, then you should do: , so you get: .
The parametric equations X = -2-3t and Y= 6+4t describe the position of the particle, in meters and seconds. How does the particle's position change each second?
(-1/20 , 1/15) each minute? (-3 , 4)
What is the speed of the particle in meters per second?( 0.09m/sec)
Write parametric equations that describe this motion, using meters and minutes as units.
Are my answers correct?
I could not do the last problem. Help pls.
