Question

The expression -4.9t^2+50t + 2 represents the height, in meters, of a toy rocket t seconds after launch. The initial height of the rocket, in meters is.

Answer 1

The initial height is 2.

This equation is in the form
y = -4.9t² + v₀t + h₀, where v₀ is the initial velocity and h₀ is the initial height.  The value in place of h₀ is 2.
