Question

If a free-falling object is dropped from a height of 100 feet, and air resistance is neglected, the height h (in feet) of the object at time t (in seconds) is given by h : -16t^(2)+100 Find the velocity of the object when t = 1

Answer 1

right now you've got a displacement formula, to get a velocity formula, you need to differentiate.
\[h(t)=-16t^2+100\]\[h'(t)=-32t\]\[h'(1)=-32(1)\]\[v=-32 feet/s\]

Answer 2
