a particle starts falling from top of tower at t=0 simultaneously a car situated on ground some distance away starts moving towards the tower at a constant velocity of 5m/s the radius of curvature of the trajectory of particle as seen by observer in the jeep at some time t is 5/2*(17)3/2 metre ...FIND the time t in seconds.!!

Dear Prakhar,
the speed of the particle is= (-gt). j^
speed of car= (-5). i^
Relative velocity of the car= (-5).i^ + (gt).j^
relative acc for car= (g).j^
but v^2/R=g
Find mod v and by
putiing putting the value of value of v and R we get the ans.
sorry I didnt proceeded since i didnt understood the value of R.
Regards.

An object of mass m = 0.25 kg oscillates in a fluid at the end of a vertical spring of spring
constant kH = 85 N/m, see Fig.1. The effect of the fluid resistance is governed by the
damping constant b = 0.07kg/s.
(i) Find the period of the damped oscillation.
(ii) By what percentage does the amplitude of the oscillation decrease in each cycle?
