Justin and pedro each launched a toy rocket into the air. the height of justin’s rocket is modeled by the equation h = –16t2 + 60t + 2. pedro launched his rocket from the same position, but with an initial velocity double that of justin’s. which equation best models the height of pedro’s rocket?

Height of justin rocket , h =-

Displacement (h) = Time taken (t) × Velocity (v)

→ h = t v

Velocity of Pedro's rocket is twice of Justin rocket.

It gives , h = 2 t v

Velocity is inversely proportional with time.

So , if in the equation of Height of Justin rocket if we replace t by  , we can get height of Pedro's rocket.

H = Height of Pedro's rocket

H= -16 (t/2)² + 60 × (t/2) + 2

 = - 4 t² + 30 t + 2

is the equation that models the height of Pedro's rocket.
