small rocket is fired in a test range. It rises high into the air and soon runs out of fuel. On the way down it passes near an observer (sitting in a 20-m-high tower) who sees the rocket traveling at a speed of 30 m/s and moving in a vertical plane at an angle of 80° below horizontal. With what speed does the rocket hit the ground? _______ m/s Once the rocket passes the observer, how long does it take to hit the groun

A ball is thrown from a high window. The arc path that it takes is a result of the combination of its horizontal and vertical motions. Which statement describes the acceleration of the ball? O The ball accelerates horizontally away from the building. The ball accelerates upward away from the ground. The ball does not accelerate. The ball accelerates vertically downward toward the ground.
Please answer this question. An airplane releases a ball as it flies parallel to the ground at a height of ℎ=245 m as shown in the figure. If the ball lands on the ground a horizontal distance equal to the height ℎ from the release point, calculate the speed ? of the plane. Neglect any effects due to air resistance, and use ?=9.81 m/s2 for the acceleration due to gravity.

After discovering that two hikers have been stranded on Devil’s Thumb Pass, the Colorado Search andRescue team sends out a plane with supplies for the hikers. Because the hikers are in an isolated location, theplane has to drop the supplies as it fies overhead (see Figure 1). If the plane is 235 m above the hikers andhas a horizontal speed of 200 km/h, how far away from the hikers should the supplies be dropped if they areto land at the hikers’ location?
