Question

A ball is dropped from the top of a building.The ball takes 0.5 s to fall past the 3m length of the window some distance from the top of the building.If the velocities of the ball at the top and at the bottom of the window are vT and vB respectively,then (Take g=10m/s^2)
a.)vT+vB=12ms^-1
b.)vT-vB=4.9ms^-1
c.)vB×vT=1ms^-1
d.)vB/vT=1ms^-1
