At t = 0 s time a stone is thrown from the top of a cliff above a lake. Another stone is thrown down from the same point , 1.6 s later , with a initial velocity of 32.0 m / s. The two stones hit the water in one instant. Determine the cliff height.

A toy roller coaster contains a loop of radiusR. A toy train, which consistsof a lot of small waggons is moving towards the loop with constant velocity. The lengthof the train isL >2Rπ, and the radius of the loop is much larger than the height of thewaggons. The ...
