The speed limit in a school zone is 45 km/h. A driver traveling at this speed sees a child run onto the road 20 m ahead of his car. He applies the brakes, and the car decelerates at a uniform rate of 11.0 m/s2. If the driver's reaction time is 0.55 s, will the car stop before hitting the child?What is the stopping distance of the vehicle?

    A car is moving on a city street at a speed of 30 km/h. The driver sees a red traffic signal ahead and slams on the brakes, providing an acceleration that has magnitude 6.0 m/s2. The driver's reaction time is 0.50 s. (a) Determine the displacement of the car until it stops. ___m (b) Repeat Part (a) if the initial speed is 60 km/h and the braking acceleration is the same as in Part (a). ___m

    11.78 A car is traveling at a constant speed of 54 km/h when its driver sees a child run into the road. The driver applies her brakes until the child returns to the sidewalk and then accelerates to resume her original speed of 54 km/h; the acceleration record of the car is shown in the figure. Assuming x = 0) when t = 0, determine (a) the time t, at which the velocity is again 54 km/h, (b) the position...

    Suppose a car is traveling at +16.0 m/s, and the driver sees a traffic light turn red. After 0.225 s has elapsed (the reaction time), the driver applies the brakes, and the car decelerates at 8.00 m/s2. What is the stopping distance of the car, as measured from the point where the driver first notices the red light?

    Suppose a car is traveling at +17.6 m/s, and the driver sees a traffic light turn red. After 0.315 s has elapsed (the reaction time), the driver applies the brakes, and the car decelerates at 6.00 m/s2. What is the stopping distance of the car, as measured from the point where the driver first notices the red light?

    Please help me understand how to solve this problem 6) A driver is going 90 km/hr when he suddenly sees the stop light 40 m ahead. It takes the s before he applies the brakes. Once he does begin to brake, he decelerates at a rate of 10 m/s2 a) b) Does he stop on time? What would be the maximum speed at which the driver can go and NOT pass the stop light?

    An automobile is traveling on a long, straight highway at a steady 75.0 mi/h when the driver sees a wreck 190 m ahead. At that instant, she applies the brakes (ignore reaction time). Between her and the wreck are two different surfaces. First there is 100 m of ice, where the deceleration is only 1.30 m/s2 . From then on, it is dry concrete, where the deceleration is a more normal 8.00 m/s2 . a). What was the car’s speed...
