Question

Our nosecracker moved back and forth as shown. The kinetic energy will be greatest at point:

A)A 
B) B 
C) C

Quizplus · Accepted Answer

The kinetic energy of an object in motion is given by the equation KE=1/2mv^2, where m is the mass of the object and v is its velocity. At point B, the nosecracker is at its maximum velocity, which means it has the greatest kinetic energy. At points A and C, the velocity of the nosecracker is zero, so there is no kinetic energy.
