Question

A particle at time t = 0 started with initial velocity
of 8 m/s from a point and moves with a constant
acceleration of 2 m/s2 opposite to velocity. Find the average speed of the particle between the time
interval t = 3 sec to t = 6 sec
(a) 1 m/s
(b) 1/3 m/s
(c) 4/3 m/s
(d) 5/3 m/s​

Answer 1

ma 'am can you please give the distance between the points as

speed is equal to distance / time

we have the time but we don't have distance
