Question
The vertical position of an object is modeled by the function h(t)=-16t^2 +5t+7, where h is measured in feet and t is measured in seconds. Find the object's initial velocity (that is, the velocity at t=0).
Is it 5 feet per second?
Is it 5 feet per second?

yes
v(t) = h ' (t) = -16t + 5
so
v(0) = -16(0) + 5 = 5
v(t) = h ' (t) = -16t + 5
so
v(0) = -16(0) + 5 = 5
