A boy runs away from a pole in a straight line so that its velocity is inversely proportional to the distance from the pole. When boy is at a point A at a distance x1 = 100 m from the pole, its velocity is v1 = 2 m/s. What time will boy take to run away from point A to point B which is at a distance x2 = 200 m from the pole? (1) 50 s (2) 60 s (3) 75 s (4) 90 s

  • Kinetic energy (KE) is the energy of motion. Any object that is in motion has kinetic energy. Kinetic energy is described by the following equation, where m = mass of the object (kg) and v = velocity:

    KE1 = 1/2 x m x v2

     if you have twice the velocity for the same mass, the kinetic energy will be four times the original value. by substituting 2v (twice the initial velocity) for v in the equation:

    KE2=(1/2)m(2v)2=4((1/2)mv2)=4⋅KE1
