A model rocket is launched with an initial upward velocity of 235ft/s. The rocket's height h (in feet) after t seconds is given by the following.

h = 235t -16t^2

Find all values of t for which the rockets height is 151 feet. Round to the nearest hundredth.

-----------

When doing this problem I come up with this....

h=151

151=235t-16t^2

16t^2-235t+151=0

t = 1/32 seconds

Is this correct?
