At the moment t=0 a particle leaves the origin and moves in the positive direction of the x-axis.Its velocity at any time is `vecv=vecv_0(1-t/tau)` where `v_0=10` cm/s and `tau`=5 s. Find :
(a)the x-coordinates of the particle at the instant 6s, 10s and 20s.
(b)the instant at which it is a distance 10 cm from the origin.
(c )the distance s covered by the particle during the first 4s and 8s.
