I have the question
A bullet is fired horizontally at a speed of $65$ m/s from the top of a vertical cliff overlooking the sea. The height of the cliff is $10$ m.
Calculate:
a) The time for which the bullet is in the air before it enters the sea.
b) The speed and angle to the horizontal of the bullet when it enters the sea."
Here is my attempt:
Are these correct ? If not could you point out what I have done wrong?
