A heavy ball gun, stays at 60.0 m from a wall which is 25.0 m tall, fires a 15 kg ball at 43.0∘43.0∘ above the ground toward the wall
a) Find the minimum muzzle velocity that the ball can pass over the wall with no interruption?
b)With the same condition of part (a) and the ground at the top of the wall is level, with a constant elevation of 25.0 m above the heavy ball gun. how far does the ball land past the edge of the wall?

You throw a ball toward a wall with a speed of 25.0 m/s and a launch angle of 40° relative to the ground. The wall is 22.0 m from the point where you are standing. 1. How far above the release point does the ball hit the wall? 2. What is the velocity as the ball hits the wall? 3. When it hits, has it passed the highest point of its trajectory? 4. At the point where the ball hits...

1 (a) A ball is launched from the ground toward a tall wall of a building at initial speed v0 = 21 m/s at an angle of 39 degrees relative to the horizontal. The wall is at a distance of 29 m from the launch point. What is the magnitude of the ball's velocity vector as it hits the wall? Your answer should be in m/s, but enter only the numerical part in the answer box. (b) A ball is...

A student launches an elastic ball from the ground level directly toward a tall vertical wall....

A student launches an elastic ball from the ground level directly toward a tall vertical wall. After the first launch, the ball bounces off the wall and then hits the ground. The student notices that the launch point is equidistant from the landing point and from the wall. The student then moves the launching point 20 m in the direction perpendicular to the wall and launches the ball again. After the ball bounces off the wall and lands, the student...
