Question

A toy car of mass 5 kg moves up a ramp under the influence of force F plotted against displacement x. The maximum height attained is given by

  1. y subscript m a x end subscript equals 20 m    
  2. y subscript m a x end subscript equals 15 m    
  3. y subscript m a x end subscript equals 11 m    
  4. y subscript m a x end subscript equals 5 m    

The correct answer is: y subscript m a x end subscript equals 11 m


    Work done = Gain in potential energy
    Area under curve equals m g h
    rightwards double arrow fraction numerator 1 over denominator 2 end fraction blank cross times 11 cross times 100 equals 5 cross times 10 cross times h rightwards double arrow h equals 11 m
