Supposed a bird flies at constant V: 2.7ms-1 and drops a stone from its beaks. 2.10s later, the stone reaches the ground. what is the horizontal component and vertical component for v just before the stone strikes the ground? the answer is 2.7 and -20.6 respectively.
Here comes the real Q, if the bird reduces its speed, what would happen to the V we counted before?
the answer is: horizontal V would reduces cuz influenced by the initial velocity. V vertical stays the same cuz it is only influenced by gravity.
Initially, I also think in that way. But the problem is will the stone strikes on the same place? Is the horizontal range stays the same? and how about the time? Isn't these factors also influence vertical V? Can we make any assumption here?
