A model rocket is launched with an initial upward velocity of 57m/s. The rocket's height h (in meters) after t seconds is given
vesna_86 [32]

The  values of for which the rocket's height is 29 meters are 0.75 and -0.67.

<h3>What is a velocity?</h3>

Velocity can be described as a vector quantity having both direction and magnitude which is the distance traveled per time.

We were given the  rocket's height h  as h=57t-5t^2 which is an equation, and we were been given the height which is the value that can be input into the equation as  is 29 meters , then we can proceed to simplify the equation as

h=57t-5t^2

29=57t-5t^2

then we will have  57t-5t^2-29=0

with the use of quadratic formula the values of t are : 0.75 and -0.67

Then we can chose 0.75 seconds

Therefore, after the calculation with the use of the quadratic equation, we can come into conclusion that the values that are required in the question are 0.75 and -0.67.
