It takes the dog 1.0 s to cover that first 5.0 m. What speed is the dog traveling when it reaches the 5.0 m point? Your Answer Answer units Started 2.

Explanation / Answer

given

vo = 0 m/s
d = 5 m
t = 1 s

let a is the acceleration of the dog.

use,

d = vo*t + (1/2)*a*t^2

5 = 0 + (1/2)*a*1^2

==> a = 2*5

= 10 m/s^2

after t = 1s,

now use, v = vo + a*t

= 0 + 10*1

= 10 m/s <<<<<<<<--------------Answer
