I need someone to check my work, because I am getting very weird numbers. Just want to make sure I am doing this right...
The height of an object in meters after t seconds is given by $$H(t) = 152t - 16t^2$$.
a) When does it hit the ground?
My answer: t(152 - 16t) = 0 which means t = 0, $$t = \frac{152}{16}$$
b) What is the velocity when it hits?
152 - 304 = -152 m/s
Is this correct?
