I. igure is a map showing force lines and equal energy contours for a plane in a conservative field. The energy contours have units of J/kg. This means that the amount of energy transferred to/from the field as an object is moved depends on the mass of the object. This also means that the force acting on an object depends on the mass of the object. (a) If an object is moved from a position where its centre of mass...

QUESTION 2 ITOTAL MARKS: 20)] [10 Marks] Q 2(a) An object rests on a plane parallel to the x-y plane. A 9 N force acting in the z-direction moves this object from the point (6,3,5) to the point (11,1,7), where distance is measured in meters. (a) Determine the force vector (b) Determine the displacement vector (c) Hence, determine the work done by the force on the object. Hint: Remember that work is a scalar quantity!

From the Work/Energy theorem, the change in kinetic energy of an object ("particle") is equal to t work done on the object by all external forces: Assuming that the cart starts from rest, (w 0). find an equation for the speed of the cart v as as function of the net work on the cart W and cart mass M. (Note: requires Adobe Flash Player.) Which of the curves on the graph at left could represent the Velocity of the...
