Question

I tried this and found it really difficult please help

Answer 1

Answer:

4.75 or 4 3/4

Step-by-step explanation:

Since all values are given, we can substitute all the values into the equation to find s.

s = $ut+\frac{1}{2} at^{2} \\= (10)(\frac{1}{2}) +\frac{1}{2} (-2)(\frac{1}{2}) ^{2}\\=5 + (-1)(\frac{1}{4} )\\=5+(-\frac{1}{4} )\\=5-0.25\\=4.75 or 4\frac{3}{4}$
