A particle is thrown upwards from ground. It experiences a constant resistance force which can produce a retardation of `2 ms^-2.` The ratio of time of ascent to time of descent 13 (`g = 10 ms^-2`)

A particle is thrown upwards from ground it experiences a constant resistance force which can produce retardation of 2m/s^2 The ratio of time of ascent to the time to descent is (g=10m/s^ 2)

A particle is thrown upward from ground. It experiences a constant resistive force which can produce retardation of 6 m/ sec^2 . What will be the ratio of time of descent to time of ascent (g = 10 m/ sec^2 )

A body falls from 80 m. Its time of descent is [g = 10 ms^(-2)]
