A baseball is thrown horizontally off a cliff with a speed of 10 ms-1. What is the vertical distance, to the nearest tenth of a meter, that the ball has fallen after 4.7 seconds?
I have a problem with this question.
An arrow is shot horizontally towards point O, which is at a distance of 20.0 m. It hits point P (right below point O) 0.10 s later. What is the distance OP (in metres)?
What do i need to find? How would i know the time taken for the arrow to reach o?
