141279 A man weighing \(80 \mathrm{~kg}\) is standing on a trolley weighing \(320 \mathrm{~kg}\). The trolley is resting on frictionless horizontal rails. If the man starts walking on the trolley along the rails at speed 1 \(\mathrm{m} / \mathrm{s}\). Then after \(4 \mathrm{~s}\), his displacement relative to ground will be

141280 Which of the following are true?
I. A body having constant speed can have varying velocity.
II. Position time graphs for two objects with zero relative velocity are parallel.
III. The numerical ratio of velocity to speed of an object can never be more than one

141281 A particle starting from the origin \((0,0)\) moves in a straight line in the \((x, y)\) plane. Its coordinates at a later time are \((\sqrt{3}, 3)\). The path of the particle makes with the \(x\) - axis an angle of
