well,
v(t) = -32t
solve for t in
256 - 16t^2 = 0
A ball is dropped from the roof a building which is 256 m high. The height h of the ball at any instant t is described by
h(t) = – 16t2 + 256
Find
i) Instantaneous velocity of ball at t = 3 seconds
ii) The time taken by ball to reach the ground level.
