Should the answer be written in m/s2 or km/h2 ?

Answer 4

m/s2

Answer 5

ok

Answer 6

Answer 7

use
vt^2 = vo^2 + 2 a. s

Answer 8

vt^2 = vo^2 + 2 a. s
56.3889^2 = 0^2 + 2 . a . 2000

find a

Answer 9

are you still here @micheletheresam ?

Answer 10

vt^2 = vo^2 + 2 a. s
56.3889^2 = 0^2 + 2 . a . 2000
3179.7 = 4000a
a = 3179.7/4000
a = 0.795 m/s2

Answer 11

got it?
