Question

A mass is attached to a spring, and oscillates horizontally on a table without any friction or air drag. The speed of the mass is measured as it moves by each of the locations A, B, C, D, and E. The speed is used to calculate the kinetic energy (KE), while the position of each point is used to calculate the elastic potential energy (PEelastic). Interpret the charts below to determine the missing KE and PEelastic values. Number At position B, the elastic potential energy PEelastic IS: Number PE elastic At position D, the kinetic energy KE is: KE 120 J 30 J 120 J 60 J 120 J Scroll down for the rest of the problem..

Explanation / Answer

at position B Pelastic = 60 J

at position C KE = 90 J

1/2*K*(1.10)^2 = 120

1/2*K*(X)^2 = 60

=> 1.10/X = sqrt 2 = 1.41

=> X = 0.780 m ( distance b/w A to C)
