Amodel rocket is launched with an initial upward velocity of 151 ft/s. the rockets height "h" (in feet) after "t" seconds is given by the following. h=151t-16t squared. find the values of "t" for which the rockets height is 88 feet. round your answer to the nearest hundredth.

t=8.81s and t=0.62s

Step-by-step explanation:

Asking for H=88ft and putting units leaves us with the formula:

Which can be also written as:

We want t, and this is a quadratic formula of the form , which we know has the solutions:

So we put the relevant values (a=16ft/s^2, b=-151ft/s, c=88ft) on that equation we get:

Which for the plus sign gives t=8.81345408729s and for the minus sign gives t=0.6240459127s, which rounding to the nearest hundredth are t=8.81s and t=0.62s
