Susan throws a stone vertically downwards and, at the same time, Peter throws a stone vertically
upwards. The speed V with which both stones are thrown is the same. Neglecting air resistance,
which one of the following statements is true?
A.
The stone thrown by Susan will hit the sea with a greater speed than the stone thrown by
Peter.
B.
Both stones will hit the sea with the same speed no matter what the height of the cliff.
C.
In order to determine which stone hits the sea first, the height of the cliff must be known.
D.
In order to determine which stone hits the sea first both the height of the cliff and the
mass of each stone must be known.
