Question

Figure shows the velocity-time graph of a particle moving in a straight line. i)Find the displacement of particle at t=20s. ii)Does the particle change its direction of motion? iii)Find retardation from 40s to 80s.​

Answer 1

Answer:

Explanation:

1).displacement = are of the triangle

1/2*20*20

=200

2).yes

3).retardation=80/40

=2m/s^-2
