precal Math help, can you tell me if this question makes sense or not? please explain what they mean and how to solve this type of question
the question is: Layla bought a toy rocket. she calculated that the rocket's height as a function of time can be represented by h(t)=16t2 + 4t where h is height in feet and t is time in seconds. if the shuttle follows this, how long will it be in the air? they give no height, and do not include distance in the equation or weight of the object. how can this equation work? if the shuttle gets 0 feet in the air, won't it just be in the air for 0 seconds? yet they say the answer is .25 seconds!
