A particle starts moving from rest on a straight line.
Its acceleration a verses time t is shown in the
figure. The speed of the particle is maximum at
the instant
at
†
†
(1) ,
(3) to
† to
(2)
(4) to​

Answer 1

Explanation:

speed is maximum at t1 . because it have max. axxleration

Answer 2

Answer:Dear Student,

Acceleration of the body is given by dvdt

So, the velocity is increased by dv in each time interval dt

Throughout the graph, we see only positive acceleration. So, velocity is increased throughout and the body will have a maximum speed at the point t4
