Fig. 2.44 shows the velocity-time graph of a particle moving in a straight line.

(i) State the nature of motion of particle.
(ii) Find the displacement of particle at t = 6 s.
(iii) Does the particle change its direction of motion ?
(iv) Compare the distance travelled by the particle from 0 to 4 s and from 4 s to 6 s.
(v) Find the acceleration from 0 to 4 s and retardation from 4 s to 6 s.

Text Solution

Verified by Experts

(i) Uniformly accelerated from 0 to 4 s and then uniformly retarded from 4 s to 6 s. (ii) 6 m
(iii) No, (iv) 2 : 1(v) acceleration = 0.5 m `s^(-1)`,
retardation = 1 m `s^(-2)`.
