A roof tile falls from rest from the top of a building. An observer inside the building notices that it takes 0.10 s for the tile to pass her window, which has a height of 1.18 m. How far above the top of this window is the roof?

Assuming the 'passing the window'part
means 0.10s to go from the top to the bottom of the window...

Then the veocity will be 1.18/0.1, so 11.8m/s. Accel will be that of 'g', so 9.8 m/s^2; and the initial velocity was 0 m/s.

Use v^2=u^2+2as

Solve for s, which will be the height it has fallen.

what does "u" stand for?

In a scene in an action movie, a stuntman jumps from the topof one building to the top of another building 4.0m away. After arunning start, he leaps at a velocity of 5.0m/s at an angle of 15degrees with respect to the flat roof. Will he make it to the otherroof, which is 2.5m shorter than the building he jumps from?
