When the speed is 20 m/s, the car will skid 2.5 meters before coming to a stop.

Distance is a number that shows how far an object changes position. Speed is a quantity that shows how fast an object is moving. Time is the interval between two states/events, or it can be the duration of an event.

The formula for time is t = s : v

With

t is time
v is speed
s is the mileage

On this question:

s = 1 m, v = 10 m/s, t = ?

t = 1 : 10

t = 0.1 second

Then the stopping time of the car is 0.1 s

To calculate the distance traveled when the car stops at a speed of 20 m/s. The first step is to calculate the acceleration first

v1 = 20 m/s, v0 = 10 m/s, t = 0.1 s

a = (v1 – v0) /t

a = (20 – 10)/ 0.1

a = 10/0.1

a = 100m/s

Next, calculate the distance the car stops when the speed is 20 m/s

s = Vo. t + ½ at^2

s = 20. 0.1 + ½ (100) 0.1

s = 2 + 0.5

s = 2.5 meters

So, the car will skid before stopping is 2.5 m
