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?

The speed of car increases two times,the kinetic energy increases

Answers:

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:
KE_{1} = 1/2 x m x v^{2}
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:
KE_{2=}(1/2)m(2v)^{2}=4((1/2)mv^{2})=4⋅KE_{1}
