An object is rolled up an incline with an initial velocity. After 3.0s it had slowed to 8.0 m/s [up the ramp]

a) Sketch a graph of the velocity vs. time. Label what you can on the graph.

b) If the object has an acceleration of 1.5 m/s [down the ramp] find the velocity at 5s.

c) Calculate the displacement after 9s. Does this make sense...explain?

d) How long until the displacement is zero?
