9. The tolerance is -+ 1 in the 3rd significant digit.

A single force acts on a 3.2 kg particle-like object in such a way that the position of the object as a function of time is given by x = 0.66t - 1.5t2 + 2.0ts, with x in meters and t in seconds. Find the work done on the object by the force from t = 0 to t = 1.2 s. Number i UnitsA 4.00 kg block is pulled up a frictionless inclined plane by a 67.0 N force that is parallel to the plane, starting from rest.The normal force on the block from the plane has magnitude 17.5 N.What is the block's speed when its displacement up the ramp is 2.40 m?
