I am stuck on this homework question can i have some help please?

A car is traveling at 13ms-1. It is allowed to slow down naturally without applying the brakes. The distance traveled in coming to rest is 640m.

Show that the average deceleration of the car is about 0.1ms-2.

What have you tried thus far?

Welcome to the board! :)

Ok, here's a little help, since it comes to rest, the final velocity should be 0m/s. Now you have initial velocity, final velocity & displacement, try applying the suitable equation of motion.

But as Hootenanny said, you need to show us your attempts before asking for any help. Take care of that and have a look at the rules. :smile:
