Don't get fooled
An object is launched from a catapault at 100 m/s at a wall at an angle of 30 degrees from the horizontal. The wall is 200 meters away. The object hits the wall and no energy is lost. The ball bounces off and lands on the ground how far away from the catapault? This problem is invented by me.
Details: Let g=10 m/s^2 Answer to the nearest meter.
