1) 90m
2) 70m
3) 20m
4) 45




say me the answer​

Answer 1

Answer:

45 m

Explanation:

on second equation of motion

u =0

t =3

a = 10

don't forget to give me heart

Answer 2

Answer:

(4) 45 m is the correct answer

Explanation:

By using , v =u+at

0=u-10×3

u=30m/s

Now, s=ut+1/2 at^2

s=30×3+1/2×-10×3×3

s=90-45

s=45m

I hope this helpful to you
