The 130-kg crate shown is on a smooth horizontal plane and
has an initial velocity of 3 m/s. A towing force of 200 N is
applied at an angle of 45° for 5 s. Determine the final velocity
(m/s) after 5 s.

Hint: From the derivation F=ma, it requires same line of action
(or at the same axis).
A robot arm moves in the vertical plane so that the 0.14-kg cylinder P travels in a circle about point B, which is not
moving. Know that arm BP starts from rest in a horizontal position and that the speed of Pincreases at a constant rate
of 200 mm/s².

4. A 3-kg ball is attached to a rope connected to the center of a table and initially travelling in a circle
of constant radius 4 m with a speed of 3 m/s. The rope is then pulled inward through a hole in the
center of the table with a constant speed of 1 m/s. Determine the ball's velocity and speed at the
instant that its distance from the center of the table is 2 m. Also calculate the amount of work done
by the rope. Neglect friction.
