Answer 1

solve the following by a quadratic equation and then solving it.

a rocket is projected vertically upwards from ground level, its height "h" meters after "t" seconds is given by the formula

h=35t-5t^2

how long does it take to reach 50 meters?

you should have two answers, explain the meaning of the two answers.

thanks
