The wall is placed 2 m away from the launcher, and the top hole is 1.5 m above the launcher. The holes are designed in such a way that the ball will only go through if it is traveling horizontally when it reaches the hole. You can adjust the launch speed and angle of the ball. What settings for the speed and angle (measured from the horizontal) should you set the launcher in order to get the ball in the hole?

A baseball player hits a home run, and the baseball just clear a wall 27 m located 144 m from the home plate. The ball is hit at an angle of 38 degrees to the horizontal, and air resistance is negligible. Assume the ball is hit at a height of 1.0 m above the ground. What is the initial speed of the ball? (use g = 10 m/s2). How much time does it take for the ball to reach the...

A trained dolphin leaps from the water with an initial speed of 12 m/s. The trainer releases the ball at the horizontal distance of 6.49 m away and the vertical distance of 4.06 m above the water. Suppose the dolphin's launch angle is 45.0 ∘. a)What is the vertical distance between the dolphin and the ball when the dolphin reaches the horizontal position of the ball? We refer to this as the "miss distance." delta h=?m b) If the dolphin's...

A rocket is fired at a speed of 75.0 m/s from ground level, at an angle of 55.1° above the horizontal. The rocket is fired toward an 11.0 m high wall, which is located 28.0 m away. The rocket attains its launch speed in a negligibly short period of time, after which its engines shut down and the rocket coasts. By how much does the rocket clear the top of the wall?
