A particle is thrown upwards from ground. It experiences a constant air resistance which can produce a retardation of 2 ms^−2 opposite to the direction of velocity of particle. The ratio of time of ascent to time of descent is (g= 10 m/s^2 )

A ball is dropped from the top of a building. The ball takes 0.5s to fall past the 3m height of a window some distance from the top of the building. If the speed of the ball at the top and at the bottom of the window are VT and VB respectively, then (g = 9.8m/s^)
