## Homework Statement

a car is moving forward at 60 km/h [E 45° N], executes a turn and is now moving at 35 km/h [N 80° W]. If the turn takes 8 seconds to complete the turn what is the average acceleration of the car in m/s?

## Homework Equations

v2 = v1 + a(t)

## The Attempt at a Solution

v2 = 35

v1 = 60

t = 8

a = ?

v2 = v1+ a(t)

35km/h = 9.72 m/s

60km/h = 16.6 m/s

35 = 60 + a(8)

35-60 = 8a

a= -3.125m/s

i'm not sure if its right, because don't you accelerate positively when you change direction
