I tried to solve this question by asumming that t30 = t10 + 4s and I found that the value of v30 is negative. So I try another way to solve it. This time I do not assume t30 = t10 + 4s. I find out all the values besides t first and finally I got the value of v30 is positive . However, t30 is not equal to t10 + 4s .

:grumpy: :grumpy: :grumpy:

What`s wrong actually??
