Question
A particle moving in a striaght line with uniform deceleration has a velocity of 40m/s at point P. 20m/s at point Q and finally come at rest at point R where QR is equal to 50m. calculate the distance PQ. ii, time taken for PQ,. iii, time taken for PR.

a = v^2/2x (use QR segment)
since a is constant use it for i and ii
eg. x = (vf^2 - vi^2)/2a
since a is constant use it for i and ii
eg. x = (vf^2 - vi^2)/2a
