Amodel rocket is launch from the ground with initial velocity of 352 ft/sec how long will it take the rocket to reach its maximum height show all work in the space provided

check the picture below. So the rocket reaches its height at its vertex.

the rocket is being launched from the ground, and therefor its initial height is 0, thus

so we can get the vertex coordinates by using its coefficients, how many "t" seconds will it take?  well, that'd be the x-coordinate of its vertex.

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
