Answer:
She would travel 175.5 m in the same amount of time
Explanation:
Here is the complete question:
Seven bicyclist are racing. Each bicyclist rides for 9s. If a bicyclist, with initial velocity of zero, steadily gained speed until reaching a final velocity of 39m/s, how far would she travel during the race in the same amount of time)?
Explanation:
To determine how far she would travel in the same amount of time, that is the distance she would cover in the same amount of time
From the question,
The bicyclist has an initial velocity of zero
That is, u = 0 m/s
and a final velocity of 39 m/s
That is, v = 39 m/s
Each bicyclist rides for 9s,
She also traveled for the same amount of time
that is, t = 9s
To determine the distance,
From one of the equations of motion for linear motion
s = t(u + v)
Then
s = (9)(0+39)
s = 4.5 (39)
s = 175.5 m
Hence, she would travel 175.5 m in the same amount of time
