V = u + at

u=2

a = - 5

t = 1/2

what is the value of v?

if i did this right the answer is v = - 0.5

Step-by-step explanation:

first you have to substitute the numbers in for the variables

v = u+at turns into v = 2+-5 (1/2)

next you multiple - 5 by 1/2 to get -.25 so the equation turns into v = 2+-2.5

last you add 2 and - 2.5 so v = - 0.5
