In a 100. m race, lisa crosses the finish line after 11.5 s. accelerating uniformly, lisa took 2.00 s to attain maximum speed, which she maintained for the rest of the race. what was lisa's acceleration?

4.76 m/s²

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

Now, this velocity will be the velocity of the later 11.5-2 = 9.5 seconds with no acceleration so,

Distance = Speed × Time

⇒ D = 2a×9.5 = 19a m

Distance traveled during the first two seconds is

Total distance = 100 m = Distance traveled in 2 seconds + Distance traveled in the 9.5 seconds

100 = 2a+19a

Acceleration during the first two seconds is 4.76 m/s².

answer; i believe the correct answer is (a) the correlation between the cause variable and outcome variable is zero;

the answer to your question is,
