Answer:
13.5 m/s
Step-by-step explanation:
To start off, simply plug in the values into the equation. This is shown below...
<u>v = velocity</u>
<u>u = initial velocity</u>
<u>a = acceleration</u>
<u>t = time</u>
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
<u>Your answer is 13.5 m/s</u>
