Question

S = ut + ½ at² u = 10 a = -2 t= ½ what would s equate to?

Answer 1

Answer:

s = 6 1/2

Step-by-step explanation:

Answer 2

Answer:

s = $\frac{19}{4}$

Step-by-step explanation:

Substitute the given values for u, a and t into the formula

s = 10 × $\frac{1}{2}$ + ($\frac{1}{2}$ × - 2 × ($\frac{1}{2}$ )² )

  = 5 + (- 1 × $\frac{1}{4}$ )

  = 5 + (- $\frac{1}{4}$ )

   = 5 - $\frac{1}{4}$

   = $\frac{20}{4}$ - $\frac{1}{4}$

   = $\frac{19}{4}$ ( = 4.75 )
