Answer:

23.8 m

Explanation:

The distance travelled by the zebra can be calculated by using the equation:

[tex]d=ut+\frac{1}{2}at^2[/tex]

where

u is the initial velocity

t is the time

a is the acceleration

For this zebra,

u = 0 since it starts from rest

[tex]a=1.9 m/s^2[/tex] is the acceleration

Substituting t = 5 s, we find the distance travelled by the zebra:

[tex]d=0+\frac{1}{2}(1.9)(5)^2=23.8 m[/tex]
