Answer and explanation:
V originally equals u + at, but when you plug in u, a, and t you get a number answer.
u = 2
a = 15
t = 1/5
Rewrite the expression with the numbers plugged in.
V = (2) + (15)(1/5)  <em>Multiply 15 by 1/5</em>
V = 2 + 3  <em>Add 2 and 3 together</em>
V = 5
<h2><u>So V would equal 5</u></h2>
