Question

S = ut + 1/2 at squared

U = 10 a= -2 t = 1/2


What is the value of S?

Answer 1

S =
`(19)/(4)`

Explanation:

Given

S = ut +
`(1)/(2)` at² ← substitute given values into expression

S = (10 ×
`(1)/(2)` ) + (
`(1)/(2)` × - 2 × (
`(1)/(2)` )² )

= 5 + (- 1 ×
`(1)/(4)` )

= 5 + (-
`(1)/(4)` )

= 5 -
`(1)/(4)`

=
`(19)/(4)`
