Question
The figure below shows the x(t) curves for three experiments involving a particular spring-box system oscillating in SHM. (a) Rank the curves according to the system's angular frequency, greatest first (use only the symbols > or =, for example 1>2=3). (b) Rank the curves according to the spring's potential energy at t = 0, greatest first. (c) Rank the curves according to the box's kinetic energy at t = 0, greatest first. (d) Rank the curves according to the box's speed at t = 0, greatest first. (e) Rank the curves according to the box's maximum kinetic energy, greatest first.
Explanation / Answer
a). 1>3>2 b). PE = 0.5kx^2 at t=0 3>2=1 c). 1>2>3 since KE depends on v which depends on slope of curve at t=0 d). 1>2>3 same reason as c. e). 1>3>2 max KE depends on amplitude
