Answer 1

Answer:

Time (x) = 3 secs

Step-by-step explanation:

Given equation -

$y = -x^2 + 6$

Now, at the highest point, velocity =0

Velocity = $\frac{dy}{dx}$

⇒ $\frac{dy}{dx}$ = 0

or, -2x + 6 = 0

or x= 3

Answer 2

Answer:

3

Step-by-step explanation:

y= -x^2+6x

dy/dx = -2x+6

when dy/dx=0

x=3

so

t=3
