please someone explain this with formula needed!

The acceleration of free fall on Mars is 3.7 m s–2.
If an object on Mars is launched vertically upwards with an initial speed of 40 m s–1, its
speed after 3.0 s will be

A 11 m s–1
B 29 m s–1
C 36 m s–1
D 51 m s–1

a =-3.7
u=40
t=3
v=???
v=u +at
v=40+(-3.7*3)= 28.9 =29 so answer is B right??

dude notes for u1 are useless just understand the main concept because this unit doesn't depend on how much you study it depends on how smart you are, and also try to solve question as much as you can
