Slope =<br> ; y-intercept = -3

Goshia [24]

Question is incomplete Let assume the Slope = 2

Answer:

Therefore the Equation of line is

$y=2x -3$

Step-by-step explanation:

Given:

Slope = 2 ( Assumption )

y-intercept = -3

To Find:

Equation of Line in Slope-intercept form

Solution:

Equation of Line in Slope-intercept Form is given as

$y=mx+c$

Where,

$m=Slope\\c=y-intercept$

So, substituting Slope =2 and y-intercept = -3 in above we get

$y=2\times x -3$ Which is the Required Equation of line

Therefore the Equation of line is

$y=2x -3$

A car is traveling at 20.0 m/s, and the driver sees a traffic light. turn red. After 0.530 s (the reaction time), the driver app

slava [35]

Before the driver applies the brakes ( with the reaction time ):
d 1 = v0 · t = 20 m/s · 0.53 s = 10.6 m
After that:
v = v0 - a · t1
0 = 20 m/s - 7 · t1
7 · t1 = 20
t1 = 2.86 s
d 2 = v 0 · t1 - a · t1² / 2
d 2 = 20 m/s · 2.86 s - 7 m/s² · (2.86 s)²/2 = 57.2 m - 28.6 m = 28.6 m
d = d 1 + d 2 = 10.6 m + 28.6 m = 39.2 m
Answer: the stopping distance of a car is 39.2 m.
