force of 20 N. What will be its velocity after 1 s?
​

Answer 1

Answer:

hope it helps...

mark as brainliest..

Answer 2

Answer:

..There is a small problem as you did not say the direction in which 20N is acted

if force is in same direction..then accleration is 4 m/s^2

v=u+at

then v=10+1*4=14 m/s

if force is against motion  v=u-at=6m/s
