## Homework Statement

A car drives north at 40mi/h for 10mins then turns east and goes 5min at 60mi/hr. Finally it goes southwest at 30mi/h for 6min.

a) determine the displacement

b)average velocity for this trip

## The Attempt at a Solution

x-component: 60mi/hr/60min x 5min = 5mi

y-component: 40mi/h/60min x 10mins = 6.7mi

south-west:

x-component:[(-30mi/hr cos 45°)/60mins]6min = -2.12mi

y-component: [(-30mi/hr sin 45°)/60mins]6min = -2.12mi

a) x-displacement: 5mi + (-2.12mi) = 2.88mi i

y-displacement: 6.7mi + (-2.12mi) = 4.58mi j

b)
