Ball Launched from a Horizontal Cliff#
A small ball is launched from a horizontal cliff with initial speed 2.97 \(m/s\). The side of the cliff is sloped. The ball makes contact with the cliff side after falling a vertical distance of 68.8 cm.

Part 1#
How long was the ball in the air before hitting the side of the cliff?
Answer Section#
Please enter in a numeric value in \(s\).
Part 2#
What is the value of the angle \(\theta\) shown in the figure?
Answer Section#
Please enter in a numeric value in rad.
Part 3#
What is the velocity of the ball just before hitting the side of the cliff? Give your final answer in terms of the \(x\)- and \(y\)-components of the velocity and the unit vectors \(\hat{\imath}\) and \(\hat{\jmath}\).
Please enter the coefficient of \(\hat{\imath}\) (in \(m/s\)).
Answer Section#
Please enter in a numeric value in \(m/s\).
Part 4#
What is the velocity of the ball just before hitting the side of the cliff? Give your final answer in terms of the \(x\)- and \(y\)-components of the velocity and the unit vectors \(\hat{\imath}\) and \(\hat{\jmath}\).
Please enter the coefficient of \(\hat{\jmath}\) (in \(m/s\)).
