Use the position function s(t) = -4.9t^2+200, which gives the height (in meters) of an object that has fallen from a height of 200 meters. The velocity at time t=a is given by limit t-a s(a)-s(t)/a-t.

a) find the velocity of the object when t=4
b) at what velocity will the object impact the ground?

Question

Use the position function s(t) = -4.9t^2+200, which gives the height (in meters) of an object that has fallen from a height of 200 meters. The velocity at time t=a is given by limit t->a s(a)-s(t)/a-t.

a) find the velocity of the object when t=4
b) at what velocity will the object impact the ground?
