Answer:

13.5 m/s

Step-by-step explanation:

To start off, simply plug in the values into the equation. This is shown below...

v = velocity

u = initial velocity

a = acceleration

t = time

v = u + at ---> v = 3 + 1.5(7)

First, multiply 1.5 and 7 together. By doing so, you get 10.5. Now the equation is...

v = 3 + 10.5

To finish, simply add 3 and 10.5...

v = 3 + 10.5 ---> v = 13.5

Your answer is 13.5 m/s
