If you do an illegal rolling stop at a stop sign and decrease your speed to 5 km/h, what speed will your car be at if you then accelerate at 3 m/s2 for 4 s?

You are at rest at a stop sign. There is another stop sign that is 100 meters away. Your maximum acceleration is 8 m/s/s and you maximum braking acceleration is 5 m/s/s. a. How much time do you spend accelerating? b. How much time do you spend braking? c. What is the total travel time? d. Over how much distance do you accelerate? e. Over how much distance do you brake? f. What is the total travel distance
You are travelling at city speed in your car (35 mi/h). Approaching a stop sign, you slwo down at a uniform rate and come to a stop in 3.9 seconds. From the time you step on the brakes, to when you come to a complete stop, what distance does the car travel? show all work
2. A car starts from rest at a stop sign. It accelerates at 2.5 m/32 for until it reaches a speed of 50 km/hr. (1 km/hr .278 m/s) (a) Draw a picture of this problem (not a motion diagram but a picture!) clearly indicate on your picture where you call x-0, t-0 i.e. establish a coordinate ystem. Label it with symbols representing initial positon, initial velocity, final position final time, final velocity and acceleration and include all the information you...
A car starts from rest at a stop sign. It accelerates at 3.7 m/s2 for 6.5 s , coasts for 1.9 s , and then slows down at a rate of 2.5 m/s2 for the next stop sign. How far apart are the stop signs?
A car starts from rest at a stop sign. It accelerates at 4.6 m/s2 for 7.4 s , coasts for 1.5 s , and then slows down at a rate of 3.2 m/s2 for the next stop sign. how far apart are the stop signs?
A car starts from rest at a stop sign. It accelerates at 4.0 m/s2 for 9 seconds, coasts for 4 s, and then slows down at a rate of 3.0 m/s2 for the next stop sign. Howfar apart are the stop signs?
A car starts from rest at a stop sign. It accelerates at 2.0 m/s2 for 5.6 seconds, coasts for 2.9 s , and then slows down at a rate of 1.5m/s2 for the next stop sign. How far apart are the stop signs?
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 162 m from a stop sign and traveling toward the sign at 27 m/s. At this time, the driver suddenly realizes that she must stop the car. If it takes 0.200 s for the driver to apply the brakes, what must be the magnitude of the constant acceleration of the car after the brakes are applied so that the car will come to rest at the stop sign?
A car is 137 m from a stop sign and traveling toward the sign at 25 m/s. At this time, the driver suddenly realizes that she must stop the car. If it takes 0.200 s for the driver to apply the brakes, what must be the magnitude of the constant acceleration of the car after the brakes are applied so that the car will come to rest at the stop sign?
