Answer to Question #73991 in Mechanics | Relativity for Navya

Question

A particle starts moving along a straight line with initial velocity of
25m/s, from O under a uniform acceleration of -2.5 m/s2. Deterime
(i) Velocity, displacement and the distance travelled at t= 5
sec
(ii) How long the particle moves in the same direction? What
is its velocity, displacement and the distance covered
then?
(iii) The instantaneous velocity , displacement and the distance
covered at t=15 sec
(iv) The time required to come back to O, velocity,
displacement and distance covered then
(v) Instantaneous velocity, , displacement and distance
covered at t=25 sec
