Find the initial velocity and time for a stone when it will hit a target A fixed on a wooden block
P placed at coordinate (3,1.25)metres. At t=0, the wooden block begins motion towards the right
with an acceleration of 1.5m/s
2
.At the same moment, a stone is projected with velocity u from
origin towards the falling block. The hitting is seen to be occurring at 45
o
to the horizontal by a
stationary person standing on ground for the stone during its downward motion.
