suppose that a baseball is tossed straight upward and that its height (in feet) as a function of time (in seconds) is given by the formula h(t)=128t-16t.

Question

find the instantaneous velocity at time t = 2

Answer 1

 

The formula should be 128t - 16t², to find instantaneous velocity, take the derivative and then plug in 2 for t.

 

128-32(2) = 64 ft/sec
