V= u + at

U=1
T= 1/2
a=-3

Work out the value of v.


Sagot :

1 + -3 1/2 is = to -2.5 so v= -2.5

Answer:

v = - [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

substitute the given values into the equation

v = 1 + ( - 3 × [tex]\frac{1}{2}[/tex] )

  = 1 + ( - [tex]\frac{3}{2}[/tex] )

 = 1 - [tex]\frac{3}{2}[/tex]

 = [tex]\frac{2}{2}[/tex] - [tex]\frac{3}{2}[/tex]

 = - [tex]\frac{1}{2}[/tex]
