Question

Help me plz i really cant work it out

Answer 1

Answer:

11 m/s

Step-by-step explanation:

Using v = u + at

where

v = final velocity which we want to find out

u = 3

a = 2

t = 4

v=u+at

v = 3 + 2×4

v =11 m/s

Answer 2

So v=?
The starting velocity u, and u=3m/s
The acceleration a is 2m/s^2
And it accelerates for time t=4s
So if we plug it all into the equation
v=(3m/s)+(2m/s^2)(4s)
v= (3m/s)+(8m/s)
v= 11 m/s
