A cannon is shot downward from a 195-m high cliff at an angle of 34 $\circ$ with respect to the horizontal.The initial speed is 40.0 m/s.What is its speed when it hits the ground in m/s?

Question

Quizplus · Accepted Answer

The speed when it hits the ground is found using energy conservation or kinematic equations. The vertical and horizontal components of the initial velocity are calculated, and then the final speed is determined by combining these components with the effect of gravity. The correct final speed is approximately 73.7 m/s.
