Question

use the equation below to find v, if u=15, a=8, and t=2 v = u + a t

Explanation:

Step1: Identify the formula and values

We have the formula \( v = u + at \), with \( u = 15 \), \( a = 8 \), and \( t = 2 \).

Step2: Substitute the values into the formula

Substitute \( u = 15 \), \( a = 8 \), and \( t = 2 \) into \( v = u + at \):
\( v = 15 + 8\times2 \)

Step3: Perform the arithmetic operations

First, calculate the multiplication: \( 8\times2 = 16 \)
Then, perform the addition: \( v = 15 + 16 = 31 \)

Answer:

\( v = 31 \)
