Question

V = u + at
u = 2 and a= -5 and t= 1/2
work out the value of v

Answer 1

`v = u + at \\ v = 2 + ( - 5)( (1)/(2) ) \\ v = 2 + (( - 5))/(2) \\ v = (4 + ( - 5))/(2) \\ v = ( (- 1))/(2) \\ v = - 0.5 \: m {s}^( - 1)`

-0.5 m/s is the right answer.

Answer 2

Explanation:

v=u+at

v=2+(-5)1

2

v=2-2.5

v=-0.5m/s²

hope it helps.
