Answer:
Option A
The sprinter's average acceleration is [tex]1.1m/s^{2}[/tex]
Explanation:
The sprinter's average acceleration can be found by means of the kinematic equation that corresponds to a Uniformly Accelerated Rectilinear Motion.
[tex]a = \frac{v_{2}-v_{1}}{t}[/tex] (1)
Where [tex]v_{2}[/tex] is the final velocity and [tex]v_{1}[/tex] is the initial velocity
The initial velocity of the sprinter will be zero ([tex]v_{1} = 0[/tex]) since she starts from a state of rest.
[tex]a = \frac{11m/s-0m/s}{10s}[/tex]
[tex]a = 1.1m/s^{2}[/tex]
Hence, the sprinter's average acceleration is [tex]1.1m/s^{2}[/tex]
