Sample problem 2/2
A particle moves along the x-axis with an initial velocity v =
50 m/s at the origin when t = 0. For the first 4 seconds it has no
acceleration, and thereafter it is acted on by a retarding force
which gives it a constant acceleration a, = -10 m/s² . Calculate
the velocity and the x-coordinate of the particle for the
conditions of t = 8 s and t = 12 s and find the maximum positive
x-coordinate reached by the particle.
