To find the distance traveled (S), we can use the formula:

S = Vo t + (1/2) a * t^2

Given:
Vo = 10 m/s
V = 0 m/s
t = 4 s

We know that acceleration (a) is equal to (V - Vo) / t, so:

a = (0 - 10) / 4
a = -10/4
a = -2.5 m/s^2

Now, we can substitute these values into the formula:

S = 10 4 + (1/2) (-2.5) 4^2
S = 40 + (1/2) (-2.5) * 16
S = 40 - 20
S = 20 meters

Therefore, the distance traveled by the object is 20 meters.
