Force]/[force] = Newon/Newton = 1
Answer:
true?
Explanation:
Im positive but not 100% sure wait for someone else to answer and see if they say the same.
Speed v = initial speed u + acceleration a x time t
v=u+at = 2 + 4*3 = 14 m/s
F should be 10. If The Whole top is 50cm, then we should subtract 10n and 30n which gives us 10.
Or it could be 15 if both top and bottom are 25. 10+15= 25.
the answer should be 20 seconds
