Explanation:
A)
The picture of the problem is missing: find it in attachment.
The acceleration of a body is equal to the rate of change of its velocity:
where
v is the final velocity
u is the initial velocity
is the time it takes for the velocity to change from u to v
In part A of the race, we have:
u = 0
v = 5.5 m/s (estimate)
So the acceleration is
B)
In part B of the race, we have:
u = 5.5 m/s is the initial velocity (estimate)
v = 9.5 m/s is the final velocity (estimate)
is the time interval between the two points considered
Therefore, using the equation for the acceleration, we can find the acceleration in part B:
C)
In part C of the race, we have:
u = 9.5 m/s is the initial velocity (estimate)
v = 11 m/s is the final velocity (estimate)
is the time interval between the two points considered
And therefore, the acceleration in part C of the race is:
