To stop a car, first you require a certain reaction time to begin braking; then the car slows under the constant braking deceleration. suppose that the total distance moved by your car during these two phases is 56.9 m when its initial speed is 80.0 km/h, and 25.7 m when its initial speed is 50.7 km/h. what are (a) your reaction time and (b) the magnitude of the deceleration?

Students design a model roller-coaster track. they place a rubber ball at the highest point on the track and let it go. the ball rolls along the track pulled only by the force of gravity. eventually, it comes to a stop. which change to the design will result in the ball moving the greatest distance?
