Homework Statement
A motorists drives south at 20.0 m/s for 3.0min, then turns west and travels at 25.0m/s for 2.0min and finally travels northwest at 30.0m/s for 1.00min. For this 6.00 min trip, find:
a)the total vector displacement
b) the average speed
c)the average velocity
Let the positive x-axis point east
Homework Equations
v=deltavectorR/delta-t
vector-v=d-vectorR/dt=dx/dt(i)+dy/dt(j)
vectorR=vectorR(i)+vector-velocity(t)+1/2vector-at^2
The Attempt at a Solution
I drew a diagram, to make the problem clearer. I think t=6min xi=25.om/s. But then I have two y-components
Thanks for your time
