Question

A particle is moving along a straight line from P towards Q. When it crosses the
point A, its velocity is 10 m.s
-1. After 2 s, it crosses another point B with velocity 6 m.s
-1
.If the particle moves with uniform acceleration between A and B, find the magnitude
and direction of this acceleration.​

Answer 1

Answer:

-2 ms-² deceleration towards B from A.

this means the rate of speed is decreasing from point A to point B.
