Answer:

The answer is:    

150 m

Explanation:

find acceleration first.

Vf = at + Vi

20 = a(15) + 0

a = 1.33m/s^2

x = 1/2at^2

x = 1/2 (1.33) (15)^2

x = 149.625m or round it to 150m

hope this helps

Answer:

1.33

Explanation:

We know

speed =distance travelled

time taken

so here distance travelled is 20.0 m/s

and time taken is 15.0s

now simplify

s=20.0/15.0

=4/3

=1.33

hope you understood it!
