Question
A heavy lead ball is dropped from rest from the top of a very tell tower. Neglecting the effect due to air resistance, which one of the fol2wing statements
is false?
(A) The ball falls 4.9 m during the first second that it falls.
(B) The magnitude of the velocity of the ball increases by 9.8 m/s for each second that the ball falls.
At time t= 2.0 s, the position of the ball is 19.6 m below its initial position.
(D At time t= 1.0 s, the instantaneous speed of the ball is 4.9 m/s.
A package is dropped from a helicopter moving upward at 15 m/s. If it takes 16.0 s before the package strikes the ground, how high
above the ground was the package when it was released? (Disregard air resistance.)
(A 1700 m
(B) 1000 m
(c) 980 m
(D) 1500 m
