Question

An object is thrown between two tall buildings 180 m from each other. The object is thrown horizontally from a window 55 m above ground from one building to a window 10.9 m above ground in the other building. Find out the speed of projection in m/s. (Use g=9.8 m/s2)

Solution


Height through which the object falls =(5510.9) m=44.1 m
Time taken for a body projected horizontally to fall through height h,
t=2hg=2×44.19.8
t=3 sec
Horizontal range R=ut
i.e 180=u×3 where u is the speed of projection.
u=60 m/s
