two drivers, alison and kevin, are participating in a drag race. beginning from a standing start, they each proceed with a constant acceleration. alison covers the last 1/4 of the distance in 3 seconds, whereas kevin overs the last 1/3 of the distance in 4 seconds. who wins and by how much time?

Alison wins against Kevin by 0.93 s

Step-by-step explanation:

Alison covers the last 1/4 of the distance in 3 seconds, at a constant acceleration , we have the following equation of motion

where s (m) is the total distance, ta = 3 s is the time

Similarly, Kevin overs the last 1/3 of the distance in 4 seconds, at a constant acceleration , we have the following equation of motion:

tk = 4 s is the time

Since we can conclude that , so Alison would win.

The time it takes for Alison to cover the entire track

The time it takes for Kevin to cover the entire track

So Alison wins against Kevin by 6.93 - 6 = 0.93 s

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
