When maggie applies the brakes to her car, it slows uniformly from 15.0 m/s to 0.0 m/s in 2.50s. how many meters before the stop sign must she apply her brakes in order to stop at the stop sign?

We have that the distance in meters before the stop sign must she apply her brakes in order to stop at the stop sign

s=18.8m

From the question we are told that

It slows uniformly from 15.0 m/s to 0.0

in 2.50s

Distance, s = 18.75 meters

Explanation:

It is given that,

Initial speed of the car, u = 15 m/s

Final speed of the car, v = 0

Time taken, t = 2.5 s

We need to find the distance covered by the car before the stop sign must she apply her brakes in order to stop at the stop sign. Firstly, we will find the acceleration of the car as :

Using third equation of motion as :

, s is the distance

s = 18.75 m

So, the distance covered by the car before it comes to rest is 18.75 meters. Hence, this is the required solution.      

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.
