A truck is traveling at a constant speed of 56.6 km/h . Suddenly, the driver sees a deer 24.0 m away and slams on the brakes. If the truck hits the deer 2.40 s after the driver slams on the brakes, what was the speed of the truck, in km/h, when the deer was struck? Assume motion was at constant acceleration.
