Question

A point moves rectilinearly in one direction as  Fig. 1.1 the distance s traversed by the point as a function of the time t.




 Using the plot find:

(a)  the average velocity of the point during the time of motion; 

(b) the maximum velocity;

(c) the time moment to at which the instantaneous velocity is equal to the mean velocity averaged over the first to seconds. 

​

Answer 1

Answer:

a). average velocity = total displacement/ total time

=2/20

= 10 m/s
