6. Formula Based Problem: A car is speeding down a highway at 30 m/s. A stray dog runs into the road ahead of the driver. The driver hits the brake decelerating at a rate of 10 m/s. The driver managed to stop the car right as it was about to hit the car. How far away was the dog when the driver first hit the brake?
7. Formula Based Problem: a baseball player hits a ball at a Vox of 20 m/s and a Voy of 20 m/s from a height of 1m. How far did it go before hitting the ground. Assume no air resistance.

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)

Suppose a wheel with a tire mounted on it is rotating at the constant rate of 2.15 times a second. a tack is stuck in the tire at a distance of 0.373 m from the rotation axis. noting that for every rotation the tack travels one circumference (a) find the tack's tangential speed. (b) what is the tacks radial acceleration?
