Question

A particle starts from rest. Its acceleration at time t = 0 is 6 m/s which varies with time as shown in fic
Find the maximum speed of the particle.
​

Answer 1

Answer:

the area of graph gives speed so the area will be 36 and 1/2 ×36 is 18

Answer 2

Answer:

Maximum speed/velocity of the particle is the area of the triangle in the enclosed graph = 1/2×6×6

=18 m/s.

HOPE THIS HELPS...(NOTE:- The particle was moving in an increasing (constant) acceleration of 6m/s^2 in time 0 second. As it decreases/retards in time t moving in uniform retardation we find the area of the triangle from the given graph).
