The way it's written, I cvan't tell if it's:
+v+=+%283%2F2%29%2At+-+5%2F2+
or
+v+=+3%2F%282t%29+-+5%2F2+
------------------------
I'll solve for both and you choose the right one
(a)
+v+=+%283%2F2%29%2At+-+5%2F2+
+v+=+%283%2F2%29%2A5+-+5%2F2+
+v+=+15%2F2+-+5%2F2+
+v+=+10%2F2+
+v+=+5+
----------------------------
(b)
+v+=+3%2F%282t%29+-+5%2F2+
+v+=+3%2F%282%2A5%29+-+5%2F2+
+v+=+3%2F10+-+5%2F2+
+v+=+3%2F10+-+25%2F10+
+v+=+-22%2F10+
+v+=+-11%2F5+
-----------------------------
Be sure which one they mean before

===========
It's ambiguous.
Add some parentheses. They're free.
