A stone is thrown horizontally from the top of a tower at the same instant a ball is dropped vertically. Which object is traveling faster when it hits the level ground below?
It is impossible to tell from the information given.
The stone.
Neither, since both are traveling at the same speed.
The ball.
A bullet is fired horizontally, and at the same instant a second bullet is dropped from the same height. Ignore air resistance. Compare the times of fall of the two bullets.
cannot tell without knowing the masses
The fired bullet hits first.
They hit at the same time.
The dropped bullet hits first.
A rifle bullet is fired at an angle of 300 below the horizontal with an initial velocity of 800 m/s from the top of a cliff 80 m high. How far from the base of the cliff does it strike the level ground below?
140 m.
150 m.
160 m.
130 m.
