Question 1114350
The way it's written, I cvan't tell if it's:
{{{ v = (3/2)*t - 5/2 }}}
or
{{{ v = 3/(2t) - 5/2 }}}
------------------------
I'll solve for both and you choose the right one
(a)
{{{ v = (3/2)*t - 5/2 }}}
{{{ v = (3/2)*5 - 5/2 }}}
{{{ v = 15/2 - 5/2 }}}
{{{ v = 10/2 }}}
{{{ v = 5 }}}
----------------------------
(b)
{{{ v = 3/(2t) - 5/2 }}}
{{{ v = 3/(2*5) - 5/2 }}}
{{{ v = 3/10 - 5/2 }}}
{{{ v = 3/10 - 25/10 }}}
{{{ v = -22/10 }}}
{{{ v = -11/5 }}}
-----------------------------
Be sure which one they mean before
