Question

A mass is oscillating horizontally on a spring. At the locations A. B. C, D, and E photogates are used to measure the speed of the mass as it moves by. The speed is used to calculate the kinetic energy (KE), while the location of the photogates is used to calculate the elastic potential energy (PEelastic). Interpret the charts below to determine the missing KE and PEelastic values. Assume all values are exact. Number At position B, the elastic potential energy PEelastic is Number elastic At position D the kinetic energy KE is KE 100 J 25 J 100 J 50 J 100 J

Explanation / Answer

As mechanical energy is conserved everywhere and it is 100 J as clear from the locations A and E in the diagram. So missing potential energy at B is 100-50 = 50 J while missing kinetic energy at D is 100-25=75 J.
