V= u + at

u=2 a= -5 t=1 half
What’s the value of v?

Prime number

Step-by-step explanation: because it doesn't have a value so yeah its a prime number.

V = 0.5

Step-by-step explanation:

V = u + at

If U = 2, a = -5, and t = 1/2, then you can replace these in the equation to make the equation: V= 2 + (-5 x 1/2)

Solve the parenthesis first. -5 times 1/2 is -2.5.

Now the equation is V= 2 + -2.5

Simplifying that even more, 2 + -2.5 is 0.5

Therefore, V = 0.5

Hope this helped!
