Question

A particle is moving along x-axis in
such a way so that its velocity vs time
graph is


Find : (a) accleration of particle at t=5sec
15 sec, 30sec,t=60 sec
(b) Displacement of particle between t=0,t=80sec
(c) Distance travelled by particle from
t=0-80sec
(d) plot accelaration vs time graph for
motion of particles​

Answer 1

distance=Total area

Area=2×2+12×2×1+12×4×2=9m

Answer :

B
