QUESTION:
A mass is vibrating at the end of a spring of force constant 225 N/m. F ? igure E14.62 shows a graph of its position x as a function of time t. (a) At what times is the mass not moving? (b) How much energy did this system originally contain? (c) How much energy did the system lose between t = 1.0 s and t = 4.0 s? Where did this energy go?
ANSWER:Step 1 of 3
a)
As we know that the rate of change of position with respect to the time is equal to the speed of the mass. At the minima and maxima, the slope will be zero in the given graph.
Thus, the speed of the mass will be zero one second apart starting with zero second.
