A crow flying at 2 m s in the horizontal direction (parallel to the flat ground) opens its beak to caw at another bird and accidentally drops a piece of bread he was carrying, from a height of 10m above the ground. The bread is released with no initial vertical velocity.
(a) How long does it take for the bread to hit the ground?
(b) How far does the bread travel horizontally before it lands?
(c) What is the velocity (both components, or magnitude and direction) of the bread just before it hits the ground?
(d) What is the speed of the bread just before it hits the ground?
