and @ kimdaemin oppa I'm fine
what about you Both
you Both of me remember ( ･ั﹏･ั)( ･ั﹏･ั)​

Answer 1

Answer:

Since, Force = 4N M x A = 4N (f=ma) 16kg x A = 4N. (m = 16kg) [ A = -1/4 m/s² ] Now, From 1st eq. of motion v = u+at 0 = 10 + (-1/4)t t = -4 x -10 [ t = 40 sec]

Answer 2

Answer:

hey amigo

how are you ?

hope you remember me :(
