use the equation below to find v, if u = 14, a = 7, and t = 3. v = u + at

Explanation:

Step1: Substitute given values

Substitute $u = 14$, $a = 7$, and $t = 3$ into $v=u + at$. So we get $v=14+7\times3$.

Step2: Calculate the product

First, calculate $7\times3 = 21$. Then the equation becomes $v=14 + 21$.

Step3: Calculate the sum

$14+21=35$.

Answer:

$35$
